Dear BioStars,

I am trying to run FusioMap to detect candidate fusions in a paired end RNASeq data set. I have already tested this dataset with a few other fusion algorithms and received no error (so am sure the .fastq files are not corrupted). But when running with FusionMap I get this error. 
I hope you can help me understand what this error is actually referring to? and how I can resolve this?

Many thanks for your time in advance!

It looks like you're trying to read gzip-compressed data when the data is in fact not gzip-compressed. If there's such an option, try telling your program that the files are not compressed or compress your files with gzip first.

Thanks. In fact when I gzipped the data, the error was gone. Now I have an understanding what "first magic byte error" was referring to!
