Hi @VROUX
As a guess, errors like this
can indicate one of these problems:
-
A mismatch between the input files. Meaning, data in one file is not labeled the same was as in another file. For this case, this could be how the fasta
>
title lines are formatted. Or if the data is in a collection folder, how the element identifiers are formatted. You could modify and simplify these formats across all inputs. If a sequence is labeled a certain way in one file, then all files need to have the same sequence labeled that same way. -
A problem with the tool as installed on the server where you are working. This is something the administrators would address. Sending in a bug report is one way to directly report it.
We can try to help to determine which is going on with your runs. The link you shared is to a local IGV display. Instead, try sharing the Galaxy history itself. The FAQ I linked above explains how to generate the link. You can post it back here, then unshare once we are done.
Thanks!
