Getting multiple CAS types for a single CRISPR array #27

Closed annagaines closed 3 years ago

annagaines commented 3 years ago

What does it mean multiple cas systems/types are reported in overlapping positions? Below is an example from the CRISPR-Cas_summary.tsv of my results.

Sequence(s) CRISPR array(s) Nb CRISPRs Evidence-levels Cas cluster(s) Nb Cas Cas Types/Subtypes

Hi @annagaines , Thank you for your message. I had not seen this message before. It is interesting! However, I don't know how to interpret it! Maybe you could try the online version or other tools to see if you get same results? Best, david
