WebYou can run bowtie2 with default settings, but employ '-k 2', which will report up to two mapped location per read/pair. The resulting SAM file can then be filtered using the XS:i flag, which indicates the second best mapping location, i.e. it identifies non-uniquely mapping reads. Below is some dummy code to illustrate: WebUnited States. Hi Mayank, The best option I know of is to do the following: 1 - obtain the sequence identifiers for the unmapped reads by filter the SAM file, then cutting them out 2 - convert the original FASTQ file to FASTA - you should get two output, one for the sequences and one for the quality score values 3 - use the tool "Fetch ...
