2.3 Step 1: Clustering with clusterMany

clusterMany lets the user quickly pick between many clustering options and run all of the clusterings in one single command. In the quick start we pick a simple set of clusterings based on varying the dimensionality reduction options. The way to designate which options to vary is to give multiple values to an argument. Due to a bug in R, we need to set getClass.msg=FALSE or otherwise a slew of annoying warnings will spit out at every call; this should be fixed in the next patch to R.

Here is our call to clusterMany:

This plot shows the samples in the columns, and different clusterings on the rows. Each sample is color coded based on its clustering for that row, where the colors have been chosen to try to match up clusters across different clusterings that show large overlap. Moreover, the samples have been ordered so that each subsequent clustering (starting at the top and going down) will try to order the samples to keep the clusters together, without rearranging the clustering blocks of the previous clustering/row.

Notice that we also added the sampleData argument in our call, indicating that we also want to visualize some information about the samples saved in the colData slot (inherited from our original fluidigm object). We chose the columns “Biological_Condition” and “Cluster2” from colData, which correspond to the original biological condition of the experiment, and the clusters reported in the original paper, respectively. These are shown at the bottom of the plot.

Notice that some samples are white. This indicates that they have the value -1, meaning they were not clustered. This is from our choices to require at least 5 samples to make a cluster.

We see that the order in which the clusters are given to plotClusters changes the plot greatly. There are many different options for how to run plotClusters discussed in in the detailed section on plotClusters, but for now, this plot is good enough for a quick visualization.

The default result of combineMany is not usually a great choice, and certainly isn’t helpful here. The clustering from the default combineMany leaves most samples unassigned (white in the above plot). This is because the default way of combining is very conservative – it requires samples to be in the same cluster in every clustering to be assigned a cluster. This is quite stringent. We can vary this by setting the proportion argument to indicate the minimum proportion of times they should be together with other samples in the cluster they are assigned to. Explicit details on how combineMany makes these clusters are discussed in the section on combineMany.

So let’s label the one we found “combineMany, default” and then create a new one. (Making an informative label will make it easier to keep track of this particular clustering later, particularly if we make multiple calls to the workflow).

We see that more clusters are detected. Those that are still not assigned a cluster from combineMany clearly vary across the clusterings as to whether the samples are clustered together or not. Varying the proportion argument will adjust whether some of the unclustered samples get added to a cluster. There is also a minSize parameter for combineMany, with the default of minSize=5. We could reduce that requirement as well and more of the unclustered samples would be grouped into a cluster. Here, we reduce it to minSize=3 (we’ll call this “combineMany,final”):

This visualization can help in determining whether to change the value of proportion (though see combineMany for how -1 assignments affect combineMany).

2.5 Step 3: Merge clusters togeth ## mergeClusters run? No

Now we are ready to actually merge clusters together. We now run mergeClusters that will go up this hierarchy and compare the level of differential expression (DE) in each pair. In other words, if we focus on the left side of the tree, DE tests are run, between 1 and 3, and between 6 and 8. If there is not enough DE between each of these (based on a cutoff that can be set by the user), then clusters 1 and 3 and/or 6 and 8 will be merged. And so on up the tree.

It is useful to first run mergeClusters without actually creating any merged clusters so as to preview what the final clustering will be (and perhaps to help in setting the cutoff).

Notice that mergeClusters combines clusters based on the actual values of the features, while the coClustering plot shows how often the samples clustered together. It is not uncommon that mergeClusters will merge clusters that don’t look “close” on the coClustering plot. This can be due to just the choices of the hierarchical clustering, but can also be because the two merged clusters are not often confused for each other across the clustering algorithms, yet don’t have strong differences on individual genes. This can be the case especially when the clustering is done on reduced PCA space, where an accumulation of small differences might consistently separate the samples (so the two clusters are not “confused” as to the samples), but because the differences are not strong on individual genes, mergeClusters combines them. These are ultimately different criteria.

Finally, we can do a heatmap visualizing this final step of clustering.

plotHeatmap(ce,clusterSamplesData="dendrogramValue",breaks=.99,
             sampleData=c("Biological_Condition", "Cluster1", "Cluster2"))

By choosing “dendrogramValue” for the clustering of the samples, we will be showing the clusters according to the hierarchical ordering of the clusters found by makeDendrogram. The argument breaks=0.99 means that the last color of the heatmap spectrum will be forced to be the top 1% of the data (rather than evenly spaced through the entire range of values). This can be helpful in making sure that rare extreme values in the upper range do not absorb too much space in the color spectrum. There are many more options for plotHeatmap, some of which are discussed in the section on plotHeatmap.

              axisLine=-1)
-

+

We have seen that we can get very different plots depending on how we order the clusterings, and what clusterings are included. The argument whichClusters allows the user to choose different clusterings or provide an explicit ordering of the clusterings. whichClusters can take either a single character value, or a vector of either characters or indices. If whichClusters matches either “all” or “workflow”, then the clusterings chosen are either all, or only those from the most recent calls to the workflow functions. Choosing “workflow” removes from the visualization both user-defined clusterings and also previous calls to the workflow that have since been rerun. Setting whichClusters="workflow" can be a useful if you have called a method like combineMany several times, as we did, only with different parameters. All of those runs are saved (unless eraseOld=TRUE), but you may not want to plot them.

If whichClusters is a character that is not one of these designated values, the entries should match a clusterType value (like clusterMany) or a clusterLabel value (with exact matching). Alternatively, the user can specify numeric indices corresponding to the columns of clusterMatrix that provide the order of the clusters.

par(mar=plotCMar)
 plotClusters(ce,whichClusters="clusterMany",
                main="Only Clusters from clusterMany",axisLine=-1)

We can also add to our plot (categorical) information on each of our subjects from the colData of our SummarizedExperiment object (which is also retained in our ClusterExperiment object). This can be helpful to see if the clusters correspond to other features of the samples, such as sample batches. Here we add the values from the columns “Biological_Condition” and “Cluster2” that were present in the fluidigm object and given with the published data.

4.1.1 Saving the alignment of plotClusters

plotClusters invisibly returns a ClusterExperiment object. In our earlier calls to plotCluster, this would be the same as the input object and so there is no reason to save it. However, the alignment and color assignments created by plotClusters can be requested to be saved via the resetNames, resetColors and resetOrderSamples arguments. If any of these are set to TRUE, then the object returned will be different than those of the input. Specifically, if resetColors=TRUE the colorLegend of the returned object will be changed so that the colors assigned to each cluster will be as were shown in the plot. Similarly, if resetNames=TRUE the names of the clusters will be changed to be integer values, but now the integers will be aligned to try to be the same across clusters (and therefore not consecutive integers, which is why these are saved as names for the clusters and not clusterIds). If resetOrderSamples=TRUE, then the order of the samples shown in the plot will be similarly saved in the slot orderSamples.

As an improvement upon this, we can cluster the clusters into a dendrogram so that the most similar clusters will be near each other. We already did this before with our call to makeDendrogram.

5.1.3 Example changing the distan

Note on 0-1 clustering when subsample=FALSE We would note that the default values \(\alpha\) for the 0-1 clustering were set with the distance \(D\) the result of subsampling or other concensus summary in mind. In generally, subsampling creates a \(D\) matrix with high similarity for many samples who share a cluster (the proportion of times samples are seen together for well clustered samples can easily be in the .8-.95 range, or even exactly 1). For this reason the default \(\alpha\) is 0.1 which requires distances between samples in the 0.1 range or less (i.e. a similarity in the range of 0.9 or more). We show an example of the \(D\) matrix from subsampling; we make use of the clusterSingle which is the workhorse mentioned above that runs a single clustering command directly, which gives the output \(D\) from the sampling in the “coClustering” slot of ce. Note that the result is \(1-p_{ij}\) where \(p_{ij}\) is the proportion of times sample \(i\) and \(j\) clustered together.

ceSub<-clusterSingle(ce,dimReduce="mad",ndims=1000,subsample=TRUE,clusterFunction="hierarchical01",subsampleArgs=list(k=8),clusterLabel="subsamplingCluster",clusterDArgs=list(minSize=5))
 plotCoClustering(ceSub,colorScale=rev(seqPal5))
-

+

We see even here, the default of \(\alpha=0.1\) was perhaps too conservative since only two clusters came out (with size greater than 5).

The distances based on correlation calculated directly on the data, such as we created above, are often used for clustering expression data. But they are unlikely to have distances as low as seen in subsampling, even for well clustered samples. Here’s a visualization of the correlation distance matrix we defined above (using Spearman’s correlation) on the top 1000 most variable features:

dSp<-spearDist(t(transform(ce,dimReduce="mad",nVarDims=1000)))
 plotHeatmap(dSp,isSymmetric=TRUE,colorScale=rev(seqPal5))
-

+

We can see that the choice of \(\alpha\) must be much higher (and we are likely to be more sensitive to it).

Notice to calculate the distance in the above plot, we made use of the transform function applied to our ce object to get the results of dimensionality reduction. The transform function gave us a data matrix back that has been transformed, and also reduced in dimensions, like would be done in our clustering routines. transform has similar parameters as seen in clusterMany,makeDendrogram or clusterSingle and is useful when you want to manually apply something to transformed and/or dimensionality reduced data; and you can be sure you are getting the same matrix of data back that the clustering algorithms are using.

Comparing distance functions with clusterMany Now that we have defined the distances we want to compare in our global environment, we can give these to the argument “distFunction” in clusterMany. They should be given as character strings giving the names of the functions. For computational ease for this vignette, we will just choose the dimensionality reduction to be the top 1000 features based on MAD and set K=8 or \(\alpha=0.45\). We will save these results as a separate object so as to not disrupt the earlier workflow.

5.2 Create a unified cluster from

As mentioned in the Quick Start section, the default option for combineMany is to only define a cluster when all of the samples are in the same clusters across all clusterings. However, this is generally too conservative and just results in most samples not being assigned to a cluster.

Instead combineMany has a parameter proportion that governs in what proportion of clusterings the samples should be together. Internally, combineMany makes a coClustering matrix \(D\). Like the \(D\) created by subsampling in clusterMany, the coClustering matrix takes on values 0-1 for the proportion of times the samples are together in the clustering. This \(D\) matrix is saved in the ce object and can be visualized with plotCoClustering (which is just a call to plotHeatmap). Recall the one we last made in the QuickStart, with our last call to combineMany (proportion=0.7 and minSize=3).

plotCoClustering(ce)
-

+

combineMany performs the clustering by running a “01” clustering algorithm on the \(D\) matrix of percentage co-clustering (the default being “hierarchical01”). The alpha argument to the 01 clustering is 1-proportion. Also passed to the clustering algorithm is the parameter minSize which sets the minimum size of a cluster.

We can also manually choose the set of clusters to use in combineMany with the argument whichClusters. Here we choose only the clusters that correspond to using dimensionality reduction using the most variable features. We also set minSize to be lower than the default of 5 to allow for smaller clusters

wh<-grep("nVAR",clusterLabels(ce))
 ce<-combineMany(ce,whichCluster=wh,proportion=0.7,minSize=3,
                 clusterLabel="combineMany,nVAR")
 plotCoClustering(ce)
-

+

We can compare to all of our other versions of combineMany. While they do not all have clusterTypes equal to “combineMany” (only the most recent call has clusterType exactly equal to “combineMany”), they all have “combineMany” as part of their clusterType, even though they have different clusterLabels (and now we’ll see that it was useful to give them different labels!)

wh<-grep("combineMany",clusterTypes(ce))
 par(mar=plotCMar)
 plotClusters(ce,whichClusters=rev(wh),axisLine=-1)
-

+

Treatment of Unclustered assignments -1 values are treated separately in the calculation. In particular, they are not considered in the calculation of percentage co-clustering – the percent co-clustering is taken only with respect to those clusterings where both samples were assigned. However, a post-processing is done to the clusters found from running the clustering on the \(D\) matrix. For each sample, the percentage of times that they were marked -1 in the clusterings is calculated. If this percentage is greater than the argument propUnassigned then the sample is marked as -1 in the clustering returned by combineMany.

Good scenarios for running combineMany Varying certain parameters result in clusterings better for combineMany than other sets of parameters. In particular, if there are huge discrepancies in the set of clusterings given to combineMany, the results will be a shattering of the samples into many small clusters. Similarly, if the number of clusters \(K\) is very different, the end result will likely be like that of the large \(K\), and how much value that is (rather than just picking the clustering with the largest \(K\)), is debatable. However, for “01” clustering algorithms or clusterings using the sequential algorithm, varying the underlying parameters \(\alpha\) or \(k_0\) often results in roughly similar clusterings across the parameters so that creating a consensus across them is highly informative.
