692 from 692 (100.00%) remaining chimeric reads included
0 (0.00%) assigned to more than one target

0 of 2 nonchimeric reads span the target range

Initialising CrisprRun subsample.bam

Initialising CrisprSet lenti_zeo_self_targeting:4840-5460 with 1 samples
Error in .self$.genomeToTargetLocs(target.loc, start(target), end(target),  :

Would someone be so kind to explain to me what this error message means?

This is a bug that occurs when all of the reads are mapped as chimeras, sorry!  It's now fixed in devel version 1.3.4.

Best wishes,
