Re: Licensing terms for data derived from ARB/SILVA data
Dear Sascha Steinbiss,
thanks for the information.
We discussed it and in general we agree that the HMM profiles derived
from LSURef_115_tax_silva_full_align_trunc.fasta can be distributed.
But we would like to ask you to clearly indicate that the profiles are
only free for non-commercial usage, commercial users need a licence.
The easiest approach is to add a reference to the SILVA terms of license
assigned to the software/profile.
Have a nice weekend

The main functionality is to detect rRNAs and to output their locations
in an input sequence as GFF3 features. As far as classification goes, it
does distinguish between the individual rRNAs for a given kingdom
(5S,23S,16S for bacteria; 5S,5.8S,28S,18S for eukaryotes, etc.) but does
not taxonomically classify them as being close to a particular
species. You can see example output on the web page given above.
It is basically a wrapper around nhmmer searching for a relatively
general rRNA pHMM, meant for de novo annotation.

was at the ZBH Hamburg)
