Select fields by header keywords.
wcut is intended to be very similar to the unix command line utility cut, but with words instead.
For example, suppose you have a file (feng-rpkm.txt) with the contents
With cut, you could run cut -d',' -f2 feng-rpkm.txt to get the gname column. This is easy if you only have a few fields. For a larger number of fields, it gets annoying to count columns. With wcut, you would run
$ wcut -d',' feng-rpkm.txt gname
Similar to cut, the --complement (or -v) flag will return all the columns that do not match:
$ wcut -d',' -v feng-rpkm.txt gname
If you wanted the rpkm and gname column, but in reverse order, you could run
$ wcut -d',' feng-rpkm.txt rpkm gname
See wcut --help for a full list of options.
wcut can be installed from PyPI using pip.
$ pip install wcut
