When I use bowtie 2 i get this error
What can I do ?
(ERR): bowtie2-align exited with value 137
Could you provide some more details,like the command you gave etc..
In addition to what Jeffin Rockey said, since you tagged this as "rna-seq", you should be warned that bowtie2 is not appropriate for RNAseq data. Use STAR or something similar instead.
Unless it's prokaryotic RNA-seq?
Yes its RNA seq from cow ...
Please use ADD REPLY to answer to earlier comments, as such this thread remains logically structured and easy to follow.
For RNA-seq alignment of eukaryotic genomes you need a spliced aligner, most recommended nowadays are STAR and HISAT2.
