I don't know what version of nwc2ly you're using, but I rewrote the
original one to use for converting nwc text files to liliypond. There
are instructions on how to use it here:
http://www.holmessoft.co.uk/homepage/software/NWC2LY/index.htm
This covers creating 4-part choral scores automatically - please see the
page on "voices". The instructions also link to a zip file with the
required .exe files and a document with extra commands.
Hope that helps.

I have used the nwc2ly program to begin converting NWC files that my
dear friend Larkin who recently passed away to lilypond files. I have
found that the biggest "issue" is that since the scores are 4-part
choral music, with the original having soprano and tenor voices with
stems upward, and alto and bass voices with stems downward; while the
converted lilypond file has both soprano and alto with stems the same
direction, and the same for tenor and bass.
I am not sure how to write a mwe, so I have attached a screen shot
from Frescobaldi. I would appreciate any help possible.
