Hello,
1. I suspect a trivial problem, some file/sequence naming mismatch etc.
This error is not in connections with any checking among input sequnces
in the alignment.. If you cannot find the problem please send me the
whole example.
2. It looks the pdb file is providing alternative solutions for the same
structure or segment. Unfortunately the alternatives indicated as A and
B after the atom types, which results unrecognizable atom types.
Possibly you need to correct the file not only for A or B but to remove
the duplicates.
what happens here is that in the (probably) very high resolution
structure you can see different and relatively well defined atom
occupancies in the diffraction map and consequently all the
alternatives are reported (typically two forms). As you can see in the
8. column, there are 0.75 and 0.25 occupancy values for the two form.
You can circumvent this problem by considering e.g. only the A form
which has a higher occupancy.
