+Example: 64 barcodes / asymmetric mode / 1.9M HiFi reads on a dual 64c EPYC system:
 
-    503.57s user 11.74s system 725% cpu 1:11.01 total

+    CPU Time  : 2h 14m
 
-Those 1:11 minutes translate into 0.233 milliseconds per ZMW,
-1.16 microseconds per barcode for both sides aligning forward and reverse-complement,
-and 291 nanoseconds per alignment. This includes IO.
+That's 2.4M HiFi reads processed per minute on 128 physical CPU cores, including
+IO.
 
-## Why doesn't *lima* utilize the maximum number of provided cores?
-This might be a simple IO bottleneck. With a barcode.fasta containing only a few
-barcodes, most of the time is spent reading and writing BAM files, as the barcode
-identification is too fast. Starting version 2.2.0, you can enable multi-threaded
-BAM reading by setting the number of threads via an environment variable
+## Is there a way to show the progress?
+Yes, please use `--log-level INFO`. If there is a `.pbi` file present, the
+estimated time will be shown. Otherwise, it will show progress as number of
+reads every 5 seconds.
 
-    export PB_BAMREADER_THREADS=2
 
-## Is there a way to show the progress?
-No. Please run `wc -l prefix.report` to get the number of already processed ZMWs.

+
+## Barcoded Adapter
+The most convenient way to barcode a sample is the use of barcoded adapters, as
+depicted in the [barcode design overview](barcode-design). One minor
+disadvantage is that the ligation might not be as efficient as with standard
+SMRTbell adapters, leaving some molecules only with one adapter. As barcoded
+adapter designs are inherently symmetric, we implemented ways to recover the
+demultiplexed yield from one-sided barcoded molecules with ease.
+
+As the first step, generate HiFi data with *ccs* v6.3.0 or later. This version
+will store [additional tags per
+records](https://ccs.how/faq/missing-adapters.html), indicating if the molecule
+has missing adapters on either side. The second step is to use the new
+`--hifi-preset SYMMETRIC-ADAPTERS` introduced with *lima* v2.5.0, [described
+here](/faq/hifi-presets). That's it.

+| `ASYMMETRIC`         | `--different --min-scoring-regions 2` |
+
+For barcoded adapter libraries, `SYMMETRIC-ADAPTERS` will increase demultiplexed
+yield. More info under [barcoded adapter FAQ](/faq/barcoded-adapter)

+title: Undo
+---
+
+## Undo demultiplexing
+With the introduction of *lima* v2.5.0, it is possible to undo all
+demultiplexing steps for **HiFi data**. For this, the bioconda package contains a
+new `lima-undo` binary.
+
+Example:
+
+    lima movie.hifi_reads.bam demux.consensusreadset.xml --hifi-preset SYMMETRIC --store-unbarcoded
+    lima-undo demux.consensusreadset.xml undo.bam
+
+Let's unroll what's happening. In the first line, we explicitly request to store
+the unbarcoded reads. Without this, we would not be able to recover unbarcoded
+reads. The `XML` contains all the file paths to the `BAM` files. The second call is
+to the new *lima-undo* binary that takes a `XML` or `BAM` file as input and
+ouput.
+
+Optionally, you can also provide multiple input `BAM` files with one output `BAM`:
+
+    lima-undo demux.bam demux.unbarcoded.bam undo.bam
+
+This works also with split BAM files:
+
+    lima-undo demux.bc1001-bc1001.bam demux.bc1002-bc1002.bam demux.unbarcoded.bam undo.bam
+
+## How does it work?
+*lima* v2.5.0 and later stores everything that got clipped in an internal binary
+structure in the `ls` tag. Multiple demultiplexing rounds are supported. Once
+*lima-undo* gets called, for each read the individual demultiplexing steps get
+reverted until the read is identical to the original HiFi read.
+
+## How can I check if undo results are correct?
+How to check that the result is identical:
+
+    samtools sort --no-PG -t "zm" undo.bam -o sorted.undo.bam
+    samtools view --no-PG sorted.undo.bam > undo.sam
+    samtools view --no-PG movie.hifi_reads.bam > original.sam
