Add --no-name gzip flag to compression file output

[gwaybio]

We are get annoying file diff triggers when reprocessing the pipeline, even if nothing changes in the file. This is important to fix so that we are able to isolate actual changes that result from reprocessing output data.

As @shntnu notes in #48 the reason why the gzip files are triggering positive diffs, is because of an added timestamp.

The way to remove the timestamp from the file is to pass a --no-name (-n) flag to the gzip command. See http://linuxcommand.org/lc3_man_pages/gzip1.html

Fortunately, it looks like pandas-dev/pandas#33398 has added the ability to include args to pandas gzip compression. This improvement will be included in pandas version 1.1, which is scheduled for an Aug 1 release.

Three Options

• pandas v1.1 option (assuming that it solves this problem!)
• base python option (outlined Feature selected files available, with more row annotations included #48 (comment))
• bash option (outlined Feature selected files available, with more row annotations included #48 (comment)).

For the pandas or python option, the solution should ideally live in pycytominer. I've created a stub for this at cytomining/pycytominer#83
