alignoth
A tool for creating alignment plots from bam files. The generated vega-lite plots are written to stdout per default. An example of a generated plot can be seen here The name alignoth is derived from the visualized alignments combined with the star alioth (usage of vega plots).
Usage
alignoth -b path/to/my.bam -r path/to/my/reference.fa -g chr1:200-300 > plot.vl.json
To directly generate a plot in svg, png or pdf format we advice using the vega-cli and vega-lite-cli packages:
alignoth -b path/to/my.bam -r path/to/my/reference.fa -g chr1:200-300 | vl2vg | vg2pdf > plot.pdf
To generate an interactive view within an html file use --html and capture the output to a file:
alignoth -b path/to/my.bam -r path/to/my/reference.fa -g chr1:200-300 --html > plot.html
Arguments
The following options are available when using alignoth:
| argument | short | explanation | default |
|---|---|---|---|
| bam-path | -b | The bam file to be visualized. | |
| reference | -r | The path to the reference fasta file | |
| region | -g | Chromosome and region for the visualization. Example: 2:132424-132924 | |
| around | -a | A chromosome and a base position that will define the region that will be plotted starting 500bp before and end 500bp behind the given position. Example: 2:17348 | |
| highlight | -h | Interval or single base position that will be highlighted in the visualization. Example: 132400-132500 or 132440 | |
| plot-all | -p | Plot all reads in the given region. We advise to only use this command for small bam files with a single target. | false |
| max-read-depth | -d | Set the maximum rows of reads that will be shown in the alignment plots | 500 |
| max-width | -w | Set the maximum width of the resulting alignment plot | 1024 |
| output | -o | If present, data and vega-lite specs of the generated plot will be split and written to the given directory | |
| data-format | -f | Sets the output format for the read, reference and highlight data | json |
| aux_tag | -x | Displays the given content of the aux tag in the tooltip of the plot. Multiple usage for more than one tag is possible. | |
| spec-output | If present vega-lite specs will be written to the given file path | ||
| read-data-output | If present read data will be written to the given file path | ||
| ref-data-output | If present reference data will be written to the given file path | ||
| highlight-data-output | If present highlight data will be written to the given file path | ||
| html | If present the generated plot will inserted into a plain html file containing the plot centered which is then written to stdout |
