Automated minimum read length "-m" setting

[joshuailevy]

At the moment, the default setting for the -m parameter is often too small to remove a lot of sequencing artifacts (e.g., primer dimers), but it would seem that using the actual read lengths from the dataset would be a more robust default (say, using -m 100 for a dataset with 150bp reads, possibly implemented as percentage of the expected read length?). I know a lot of users aren't aware of the importance of this parameter's value, and resulting seq outputs can potentially be impacted.

thanks for raising this issue Josh, will keep this in mind for future releases!
