Problem when using --trackline argument when control file absent

[adeschen]

When macs2 is used without a control file and with the --trackline argument, the application crashes at the call peaks step (#3 step).

Version: macs2 2.1.0.20140616 (installed using python package)

Operating system: CentOS 6

Reproduce steps: Use this command line with a valid BAM file

macs2 callpeak -t VALID_BAM_FILE.bam  -f BAM --gsize 3.3e9 -q 0.01 -n output_file  --trackline -B --SPMR 

Output example:

[user@ls32]$ macs2 callpeak -t HI.1943.008.Index_14.LCC9_CTRL_MED1_ChIP8_GB_rep1.bam  -f BAM --gsize 3.3e9 -q 0.01 -n output_file  --trackline -B --SPMR
