Recover short reads from BAM files that were mapped to genes you are interested in. It is possible to work with a single gene call, or a bunch of them. Similarly, you can get short reads from a single BAM file, or from many of them.
Go back to the main page of anvi’o programs and artifacts.
To run this program, just specify the bam files you’re looking at and the gene of interest. To do this, name the contigs-db containing your gene and the gene caller ID (either directly through the parameter
--gene-caller-id or through a file). Here is an example:
anvi-get-short-reads-mapping-to-a-gene -c contigs-db \ --gene-caller-id 2 \ -i BAM_FILE_ONE.bam \ -O GENE_2_MATCHES
The output of this will be a file named
GENE_2_MATCHES_BAM_FILE_ONE.fasta (prefix + bam file name), which will contain all short readds that aligned to gene 2 with more than 100 nucleotides.
You also have the option to provide multiple bam files; in this case, there will be an output files for each bam file inputted.
Additionally, you can change the number of nucleotides required to map to a short read for it to be reported. For example, to expand your search, you could decrese the required mapping length to 50 nucleotides, as so:
anvi-get-short-reads-mapping-to-a-gene -c contigs-db \ --gene-caller-id 2 \ -i Bam_file_one.bam Bam_file_two.bam \ -O GENE_2_MATCHES \ --leeway 50
