Hi all,
I've installed Tophat 1.3.1 following these instructions
and when I run the test command to know if the installation has gone OK
sudo tophat -r 20 test_ref reads_1.fq reads_2.fq
I get this error message
[Errno 8] Exec format error
Here you have the complete log

I've checked that Samtools, Bowtie and Tophat and they seem to be correctly installed,
Anyone knows what would be the problem? The only kind of TopHat errors I've found reported so far are I/O errors and this doesn't seem to be such kind of error.
Thanks!
What do your fastq (.fq) files look like?
It's the dataset to test tophat, I took it here

Anyway here you have two reads
