LGA pdblist


The input data for LGA processing is composed from two sets of 3D structures (atom coordinates for molecule1 and molecule2). As the result of LGA calculations the coordinates of the molecule1 will be rotated.

The list of molecules has to be prepared in the following format:

PDB_entry  [Name           [Class      [Parameters]]]
where:   PDB_entry  - PDB code (entry) of the chain from PDB, or local structure
         Name       - name you would like to use on the plot (optional)
         Class      - additional comment (e.g. class from SCOP) (optional)
         Parameters - LGA parameters for particular molecule (e.g. selected range
                      or chain) (optional)

For information about "Parameters" please check LGA parameters.

In your list you can combine the following formats:
PDB_entry
  or
PDB_entry  Name
  or
PDB_entry  Name           Class
  or
PDB_entry  Name           Class      Parameters

 
Please make sure that you select PDB entry (chains, domains) correctly.
Otherwise NO RESULTS will be calculated.
 

PDB_entry has to be in the following format:
   1cpi_A     for PDB entry: 1cpi, chain: 'A'
   1akf       for PDB entry: 1akf, chain: ' '
   1ggg*      for PDB entry: 1ggg, all existing chains are selected (chain 'A' and 'B')

or specifying NMR MODEL:
   1bve_B_5   for PDB entry: 1bve, chain: 'B', model: 5
   1rel___4   for PDB entry: 1rel, chain: ' ', model: 4

 
There are several ways how to select from given structures the set
of residues for calculations.
 
Here are some examples:
  -ch1:B                   - chain B from molecule1 is selected
  -er1:B:B                 - chain B from molecule1 is selected
  -aa1:1:317               - residues 1 till 317 from molecule1
  -gap1:152:156            - remove residues 152 - 156 from molecule1
  -aa1:45:361              - residues 45 till 361 from molecule1
  -er1:45_B:50_B           - residues 45 till 50 from molecule1 chain B
  -er1:7S_B:7_C,12_C:49_C  - selects two ranges in molecule1: the residues 7S_B (residue 7
                             insertion S from chain B) up to 7_C (residue 7 from chain C)
                             and residues 12 till 49 from chain C
