Tags reads in a BAM file based on other BAM files.
Project description
Readtagger
Tags reads in a BAM file based on other BAM files.
Installation
pip install readtagger
Usage
To tag reads in file a.bam with file b.bam and output to path output.bam, type
readtagger --tag_file a.bam --annotate_with b.bam ----output_file output.bam
This will by default tag reads with the AD, AR, BD and BR tags, where the AD tag has detail mapping information for the current read, while the BD tag has the information for the mate. AR and BR contain the aligned reference (i.e chromosome). The first letter can be changed on a per-file basis by appending “:first_letter_read:first_letter_mate” to the file path. To change the above example into X for the read and Y for the mate, run:
readtagger --tag_file a.bam --annotate_with b.bam:X:Z ----output_file output.bam
To tag one bam file using multiple alignment files, run:
readtagger --tag_file a.bam --annotate_with b.bam:A:B c.bam:C:D ----output_file output.bam
Now reads that align in file b.bam will be tagged with AR, AD and BR, BD, while reads aligned in file c.bam are marked with CR, CD and DR, DD.
Advanced usage
To see the advanced options, type:
readtagger -h
Testing
If you modify readtagger, you can run all tests by running tox:
pip install tox tox
