Hello, I have been trying to use HISAT2 to to align RNA-seq ENCODE data which I download on my device and try upload by filesystem paths as dataset in data library (they are .fastq.gz files) but after loading them I received .fastq files and as a result error in HISAT2 gzip: input_f.fastq.gz: not in gzip format 0 reads 0.00% overall alignment rate. What should I do in that case?

Thanks, Kate

Hello,

Change the datatype to be fastqsanger instead of fastqsanger.gz.

The actual content and the datatype must be a match or this error comes up. Details: https://galaxyproject.org/support/compressed-fastq/

Double check the data is really in fastqsanger format as well, to avoid other issues. This is how: https://galaxyproject.org/support/fastqsanger/

Thanks, Jen, Galaxy team

I would try importing the data into library again and explicitly setting the type to .fastq.gz (or whatever you have) to prevent Galaxy from decompressing it automatically.
