Hello,

I tried to unzip the files.

Thanks in advance for any help!

Best,

Yue

$ unzip TAM677A1_S2_L008_I1_001.fastq.gz.1
Archive:  TAM677A1_S2_L008_I1_001.fastq.gz.1
  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 TAM677A1_S2_L008_I1_001.fastq.gz.1 or
    TAM677A1_S2_L008_I1_001.fastq.gz.1.zip, and cannot find TAM677A1_S2_L008_I1_001.fastq.gz.1.ZIP, period.

Two reason I am guessing for this: 1: Either you tried downloading multiple times this same file. In that case just rename TAM677A1_S2_L008_I1_001.fastq.gz.1 to TAM677A1_S2_L008_I1_001.fastq.gz and than gunzip this file

2: Maybe this is just a part of file. your file was uncomplete or downloaded one file from a multiple source

First you need to change the name: mv TAM677A1_S2_L008_I1_001.fastq.gz.1 TAM677A1_S2_L008_I1_001.fastq.gz Then use gunzip gunzip TAM677A1_S2_L008_I1_001.fastq.gz

You can also use gunzip file_name.

[gb]

Correct me if I am wrong, but I think only this works: gunzip -S ".1" file_name

EDIT:

gunzip -S ".gz.1" file_name

[GenoMax]

It the file indeed has a .1. That probably shows that the file may have been downloded multiple times, as hinted by @devarora above.

Hello, gb,

unzip decompresses ZIP-compressed files. You have gzip-compressed files. Therefore use gzip -d to decompress, even though I would be surprised that these days any tool actually requires decompressing files manually as most (all?) can read compressed files.
