I first used: wget http://www.bioinformatics.babraham.ac.uk/projects/fastqc/fastqc_v0.11.9.zip to get Fastqc program.
Then i wanted to unzip:
unzip fastqc_v0.11.9.zip
I got a weird error saying it couldn't be found even if it was in my central directory? Anyone know why?
Archive: fastqc_v0.11.9.zip
End-of-central-directory signature not found.
Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of fastqc_v0.11.9.zip or
fastqc_v0.11.9.zip.zip, and cannot find fastqc_v0.11.9.zip.ZIP, period.

Either the file was download incorrectly, or you don't have a current enough version of unzip. Here is the MD5 checksum of that same file when I download it:
md5sum fastqc_v0.11.9.zip
output: ee7901b681bb2762d75d5a56c7ec6958 fastqc_v0.11.9.zip
Next, try file type:
file fastqc_v0.11.9.zip
output: fastqc_v0.11.9.zip: Zip archive data, at least v2.0 to extract
If you get a different output, something went wrong with the download. If you get the same result in both cases, try
unzip -h
That should tell you program version in the first couple of lines, and it needs to be higher than v2.0.
Thanks. Yeah i see, that the fastqc_vo.11.9.zip directory is empty when i did file:
fastqc_v0.11.9.zip
Maybe wget didn't download it correctly, since I used it in a computing cluster maybe?
