To whom it may concern,
I'm trying to use analysis to make assignments of an RNA that has nonstandard
nucleotides. I see that CCPNMR has the three letter codes for the nucleotides I'd
like to use, CFL, OMG, ADE, UMF, A2M, and T11, but when I click on the molecule
in the "small compounds" tab in the Molecule window, I get a message that says
"Chemical component not available locally. OK to download to local database?"
When I click "yes" I get the message "No atom coordinates are available for
chemical compound OMG" for instance. I've tried looking up OMG on EBI's website
but don't know what file I should download and to where I should save it or how to
import it into CCPNMR. I'd appreciate some advice.
Thank you,
Laura J.
