COMET HIV-1 <> COMET HIV-2 <> COMET HCV

The COMET tool rapidly classifies HCV nucleotide sequences into subtypes. You can submit your sequences either by pasting them in the form (b) or uploading them (a).

VersionChangesDate
1.1Re-added bootstrap support levels (100 samples per sequence).2016-09-22
1.0Rewritten COMET in GO (Uses much less memory, faster; improved accuracy slightly).2016-09-18
0.2new training set based on ICTV HCV Reference Sequence Alignment (2013-09-11)2013-09-18
0.1HCV subtyping & bootstrap values to assess quality of prediction2012-03-21

Maximum size of each sequence (excluding fasta) 20000 characters

(a) upload the sequences in fasta format (you can compress the file with gzip, max. 8Mo (50MB)):
