bugfix
v0.1.1
- fix bug when later chroms had larger values (see: 9f88400 and thanks @raul-w for reporting and providing a test-case).
- adjust calculation of global and per-gc bin coverage to use only non-zero bases. this improves the ratio when comparing
to the depth inside of events (which will still count zero-coverage bases) in chromosomes with sparse coverage. (thanks @raul-w
for suggesting).
