groupBy & coverageBed (v 2.26.0) confusing results #124

Closed itsvenu closed 6 years ago

Hi

Recently, I started using version 2.26 of bedtools. I observed some differences in some of the functions. But these differences are not mentioned in the docs (or I might have missed :'( ).

Here is a minimal reproducible example

cat test.bed
A     1
A     2
A     3
B     3
B     3

version v2.16.2

cat test.bed | groupBy -g 1 -c 2 -o sum
A       6
B       6

version v2.26

cat test.bed | groupBy -g 1 -c 2 -o sum
12

Also with coverageBed

head test.bed

The change in functionality in coverage is documented in the release notes and in the "Important" note at the top of the coverage tool documentation: http://bedtools.readthedocs.io/en/latest/content/tools/coverage.html

The bug in groupby is fixed in the code in the master branch of the repository. Please clone from that and compile. A new release will be available soon
