Why it is problematic during molecular replacement or any other simulation, is there any comment ?
I think that it is favor to use GUI instead of command and prepare your file as you need
There are a lot of software can be helpful in this thing as deep view , Pymol and VMD .
But may be some of them need to use a software to emulate windows interface , you can use Wine which is free in Ubuntu store .
You should check which program inserted the Anisou records (are they from anisotropic refinement or from TLS paramters?). If you don't care about the informational content of the B factors you can just grep 'ATOM' and 'HETATM' lines from your file (there is probably a prettier way with scripting).....
> grep 'ATOM' file_with_aniso.pdb > new_file_atom.pdb
> grep 'HETATM' file_with_aniso.pdb > new_file_hetatm.pdb
> cat new_file_atom.pdb new_file_hetatm.pdb > no_anisou.pdb
no, you don't need to have wine on ubuntu or other linux distrub , for running software as pymol, vwd, chimera, so for your question.
if your file is " my-pdb-with-ANISOU.pdb" one of the possibility is this command
grep -v ANISOU my-pdb-with-ANISOU.pdb > my-pdb-without-ANISOU.pdb
To remove ANISOU from a PDB text file in any linux extension, just execute the following command.
sed '/ANISOU/d' your-pdb-file-name > your-output-file-name.pdb
As an alternative, you can also use PDBest, it's multi platform. Its website: http://www.pdbest.dcc.ufmg.br/
It provides many features and can process many PDB files for the same treatment. Of course, one of them is to remove ANISOU.
grep command will work fine such as:
grep -v "ANISOU" file.pdb > file_new.pdb
