Empty .cfg after running bam2cfg.pl

Question

[shannon.soucy]

I have been trying to run bam2cfg on my bam files generated with bowtie. The first time I tried I didn't have read groups assigned, but I wasn't comparing SV between samples so it didn't really matter- but I got an empty cfg file. So I re-ran bowtie and added the @RG information, thinking this would help- it didn't I'm getting a different error now than I was before- but still an empty .cfg file!

Here is the bam file header with the @RG:

and here is the error that i'm getting when I run bam2cfg.pl:

Use of uninitialized value $lib in hash element at bam2cfg.pl line 79, <$bam> line 26.
[Thu Mar  3 15:35:38 2016 bam2cfg.pl] Closing BAM file

[Thu Mar  3 15:35:40 2016 bam2cfg.pl] Closing samtools process : 8930
Use of uninitialized value $lib in hash element at bam2cfg.pl line 195.

when I run bam2cfg.pl on the test-data I don't have "Use of uninitialized value" warnings.

Can anyone offer any suggestions as to how I need to reformat my bam files so I can get bam2cfg.pl to generate a *.cfg file??
