ERROR: Infinite or NaN

[schorlton]

Thanks for the great tool! Hitting a bit of an error...I suspect it may be because I have so few reads or they're too short but it's a bit cryptic...

Thanks for your report!
This is indeed a bug where there are too few reads. I will fix it for the next release.
For such a small FASTQ file, you can bypass the bug by using this option -mem 0.5 instead of -ntcard.

[kmnip]

Unique k-mers (k=17,c>1): 0

Since you have zero non-singleton k-mers in your reads, you will very likely run into errors in subsequent parts of the assembly workflow.

[schorlton]

Got it, thanks! Yes I expect this to fail, just expected a more graceful error/exit explaining too little data or whatever the root cause is.

[kmnip]

Yep, I agree with you. I have incorporated error message for this issue in the next release.

[kmnip]

This bug is fixed. Please see my new release of RNA-Bloom v2.0.0: https://github.com/bcgsc/RNA-Bloom/releases/tag/v2.0.0
