Hi, while running cuffdiff on two samples (so no replicates) I get the following message
> Processing Locus Chr1:258631-267891 [ ] 0%Error: sqrt(det(cov)) == 0, 0.000000 after rounding.

Error: sqrt(det(cov)) == 0, 0.000000 after rounding.
What does it mean? is it something I should worry about?
Thanks
