According to the error, it was because of the score-min function, which has 0 as the minimum score (--score-min L,0,0.9). The command for bowtie2 individually worked when I changed the function to --score-min L,0.1,0.9 (0 is replaced by 0.1).

Bowtie2 uses the SAM optional field XS: to report the alignment score for the second best alignment for this read. Here is the description from the Bowtie2 manual: Alignment score for second-best …
WebI am not aware of a method using two indices in bowtie2 but here is a simple workaround: Get human reference genome as fasta and suffix all fasta names with _human. Do the same with the mouse genome using _mouse. cat both together and build an index. Then you can later track back whether the alignment was done to human or mouse.
