v0.9.3

v0.9.3

• Big performance improvements for large scale regions
• Automatic low memory mode, memory stays low even for chromosome scale views
• Filter/count on read pattern e.g. 'filter pattern == del or pattern == dup'
• Filter/count using named sam flag properties e.g. 'filter ~proper-pair'
• Added options for tag command e.g. 'tag NM' prints NM tag from target read
• Option to output SVG image
• Coloured arcs can be drawn for SVs when loaded as a track
• Fixed longstanding issues involving Mac - Linux X-forwarding
• Several bug fixes

v0.9.1

v0.9.1

New features

• User interface for selecting commands and editing settings
• SNP frequency drawn over coverage track
• Multiple VCF files supported for labelling
• Support for GFF3, GTF, BIGWIG, BIGBED
• Tracks can be expanded and resized with mouse
• More customisation of look; slate theme, turn on/off mismatches, edges, indels
• Faster runtime ~15% on linux, 2x faster image generation
• More model organisms supported out of the box
• Use command box to search for features in tracks, or take notes
• Integration with online genome browsers using online command
• Installers for MacOS (dmg), debian (deb) and Windows (vb script)
• Open a bam file by double-clicking or using Open With (reference genome is automatically)
• Numerous bug fixes

Breaking changes

• GW_LABEL files now contain one extra column with the filename of the original variant file.
• .gw.ini file will need to be replaced.

v0.8.2

v0.8.2

Improvements:

• Added TAB hotkey to switch between image-view and alignment-view
• Added F hotkey to highlight all alignments of selected read
• A box now highlights current region when switching regions using keyboard

Bug fixes:

• Mouse clicks are accurate after window re-size
• Window resizing using SHIFT + ARROW key does not trigger key press events

v0.8.1

v0.8.1

• Fixed regression bug - filter and count commands work again

v0.8.0

• Added window resizing using SHIFT + ARROW_KEY
• New commands/CLI-options to toggle 'insertions', 'mismatches', 'edges', 'soft-clips'
• Better keyboard input
• Command box can also be accessed with '/'
• Filename also shown when mouse is over a region
• -b option can also accept glob patterns e.g. -b '*.bams'
• Long cigars are no longer printed in full
• Can use remote reference genomes from CLI

Bug fixes

• Sticky scrolling when using vcf file

v0.7.0

GW v0.7.0

Improvements:

• Near-constant memory use when drawing static images (reads are no longer buffered unless needed). This allows plotting of whole chromosomes in parallel. To plot the genome use gw hg38 -b your.bam -n -t 16 -o chrom_plots; chromosome information is extracted from the fasta.fai file.
• Region information is encoded in filenames by default, so static images can be later opened and explored dynamically.
• Default 1x1 image grid if only single image provided

v0.6.4

Minor release

Improvements / features added

• :low-mem command to toggle low mem option
• --use-raster option to force drawing on the cpu when using --no-show option

Bug fixes:

• More accurate y-position for mouse clicks
• Deletions drawn correctly when zoomed

v0.6.3

Minor release

Features added:

• Support for bigBed files
• better drawing of --track data

Bug fixes:

• unsorted bed files work
• :var: command works for bed files

v0.6.2

Minor release

Features added:

• --config option for command line to print the path to .gw.ini
• deletion dots are scaled to monitor resolution

Bug fixes:

• using --no-show -t >1 now works
• no bam mode now works again

v0.6.1

Features/Improvements:

• New --low-mem flag for command line, reduces memory by around 30%. This drops tags and qual values from sequencing data. Useful for plotting very large regions, or even entire chromosomes
• New --tlen-y and :tlen-y option/command, scales y-axis by template length in a similar way to samplot
• --cov VAL and :cov VAL can be used to threshold the coverage profile
• :var command has been updated so you can print target variant information, .e.g :var info.SU will print SU column from info
• New :snapshot command, to save screenshots. Can optional be used with a filename :s view.png or can even parse variant info into the file name e.g. :snapshot {chrom}_{pos}_{info.SU}.png
• :grid command to control the size of the image grid e.g. :grid 8x8
• Drawings arranged on pixel boundaries, so now looks a bit cleaner, especially on low res screens.

Bug fixes:

• Better border position between rows
• Out of bounds error for reference track
• Raster images work again
