missing len entry

[Former user]

running snakemake -n gives the error below. I have previously successfully used a similar setup. It appears that in commit 5ed1e53 you removed "len" from the config.yaml. Adding "len: 20" back in fixes it. I am on python 3.5.1, installed mageck, vispr and mageck-vispr using each ones github setup.py.

You are right! Sorry for the inconvenience. I have added len again in version 0.4.7, since it is still needed by the sgrna annotation script. The new version will appear on Bioconda very soon.
