Hi everyone I´m Miguel, I´m using galaxy for a scholar research. I´m having a problem using bowtie2 I get this error when I execute.

image of the error

UB4IT and UB40T are the dataset list of the RNAseq genoma = the dataset list of the chromosomes of the reference genome I´m using (Capsicum annuum/ pepper zunla in this case)

If I execute the bowtie2 using multiple dataset in the reference genome I get this

thanks for your time :)

The custom genome needs to be reformatted:

1 - Mismatch between the reference genome and the reference annotation

The identifier/annotation on the title line for the fasta sequences are currently like this:

>gi|404474503|ref|NC_018552.1| Capsicum annuum chloroplast, complete genome

But the reference GFF has the "chromosome" names like this:


These need to be an exact match. Meaning, for this reference genome sequence, the fasta must have a title line like:


2. The custom reference genome is split into several datasets.

These should be merged into a single dataset. Use the tool Concatenate to stack the individual datasets together. Then check for empty lines and reformat the sequence wrapping just to be sure all is consistent.

Thanks! Jen, Galaxy team
