Hi every body, I'm running MACS2 with this parameters and I have some warning as you can see. They are related to "d" parameter that I've never seen before. Any suggestion?
macs2 callpeak -t file1.BAM -c file2.BAM -g hs -s 36 -m 8 30 -p 0.00001 -B -n proof
WARNING @ Fri, 13 Jan 2017 13:15:07: Fewer paired peaks (815) than 1000! Model may not be build well! Lower your MFOLD parameter may erase this warning. Now I will use 815 pairs to build model!

INFO @ Fri, 13 Jan 2017 13:15:07: #2 predicted fragment length is 34 bps

WARNING @ Fri, 13 Jan 2017 13:15:07: #2 Since the d (34) calculated from paired-peaks are smaller than 2*tag length, it may be influenced by unknown sequencing problem!
WARNING @ Fri, 13 Jan 2017 13:15:07: #2 You may need to consider one of the other alternative d(s): 34,181,256,497
WARNING @ Fri, 13 Jan 2017 13:15:07: #2 You can restart the process with --nomodel --extsize XXX with your choice or an arbitrary number. Nontheless, MACS will continute computing.
