Dexseq non-stranded index error

Question

[bart]

Hi,

I want to perform differential exon usage analysis on a dataset. I want to use Dexseq to achieve this but receive the following error using the Dexseq module on galaxy.eu: 'Non-stranded index used for stranded GenomicArray'. My input was a gtf file created using a human gtf file from ensembl. I changed this gtf file per the following suggestion: https://www.seqanswers.com/forum/applications-forums/rna-sequencing/46984-problems-with-cufflinks-gtf-annotated-files-and-dexseq. I have tried using different fasta and gtf files but cannot solve this issue. Can anyone suggest an answer?

KR, Bart
