Hi Moritz, I'm sorry for the trouble! Yes, certainly if you have only 2 mutations the sequence should get aligned. Somehow it seems that your input sequence is not getting read properly, as you are guessing. Your formats sound ok. The format for a sequence file is:
optional text about this chain ONELETTERCODEFORSEQUENCE optionally start another chain NEWCHAIN
ANOTHERNEWCHAINSIGNALLEDBYEMPTYLINEABOVE
where all spaces or characters that are not amino acids are ignored,
and capitalization is ignored. You can indicate a new chain with an
empty line or with one or more ">".
If this doesn't help and you'd like to send me ([email protected])
your sequence file and the PDB file and the exact command you used I
can run it here and see what is going on.
All the best,
Tom T

Hi all, i'm currently trying to solve my structure with phenix and i tried to do it via AutoMR. At first everything works fine, it finds a MR solution, but then i get this error:
Chain too short or poor match to sequence: MYIQVLGSAAGGGFPQWNCNCVNCKGYRDGTLKATARTQSSIALSDDGVHWILCNASPDIRAQLQAFAPMQPARALRDTGINAIVLLDSQIDHTTGLLSLREGCPHQVWCTDMVHQDLTTGFPLFNMLSHWNGGLQWNRIELEGSFVIDACPNLKFTPFPLRSAAPPYSPHRFDPHPGDNLGLMVEDTRTGGKLFYAPGLGQVDEKLLAMMHGADCLLVDGTLWEDDEMQRRGVGTRTGREMGHLAQNGPGGTLEVLDGFPRQRKVLIHINNTNPILDENSPERAEVLRRGVEVAFDGMSIELL

Sorry, the PDB file and sequence file could not be aligned (with no gaps and >50.0% identity)
Please restart the wizard... You have several possibilities to try .... You can set rebuild_in_place=No You can set input_sequence_file=None You can set min_seq_identity_percent to a lower value You can set highest_resno to a higher value You can specify start_chains_list if your PDB file sequence starts with a residue number greater than the number of residues in the sequence.
what can i do now? the pdb file has nearly the same sequence (2 mutations) but he says that he can't align them, i use a .dat file for this is this correct? i also have a fasta line in it >... but it doesn't work without this line either. i tried with different phenix versions and have always the same problem Any suggestions would be appreciated.
