chfl_residue
type¶chfl_residue
¶A chfl_residue
is a group of atoms belonging to the same logical
unit. They can be small molecules, amino-acids in a protein, monomers in
polymers, etc.
The initialization routine for chfl_residue
are:
chfl_residue%init()
;chfl_residue%with_id()
;chfl_residue%from_topology()
;chfl_residue%for_atom()
;chfl_residue%copy()
.Type fields: |
|

chfl_residue%
init
(name[, status])¶Initialize the residue with a new residue with the given name
and no
residue id.
Parameters: | character (len=*) :: residue name |
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to CHFL_SUCCESS , you can learn more
about the error by using chfl_last_error . |
chfl_residue%
with_id
(name, id[, status])¶Initialize the residue with a new residue with the given name
and
residue id
.
Parameters: |
|
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to |
chfl_residue%
copy
(residue[, status])¶Initialize this residue with a copy of residue
.
Parameters: | residue [chfl_residue] :: residue to copy |
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to CHFL_SUCCESS , you can learn more
about the error by using chfl_last_error . |
chfl_residue%
from_topology
(topology, i[, status])¶Initialize this residue with a copy of the residue at index i
from a
topology
. The residue index in the topology is not always the same as
the residue id.
Parameters: |
|
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to |
chfl_residue%
for_atom
(topology, i[, status])¶Get a copy of the residue containing the atom at index i
in the
topology
.
Parameters: |
|
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to |
chfl_residue%
name
(name, buffsize[, status])¶Get the name of the residue in the string buffer name
.
The buffer size must be passed in buffsize
. This function will truncate
the residue name to fit in the buffer.
Parameters: |
|
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to |
chfl_residue%
id
(id[, status])¶Get the identifier of the residue in the initial topology file in id
Parameters: | id [integer] :: identifier of the residue |
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to CHFL_SUCCESS , you can learn more
about the error by using chfl_last_error . |
chfl_residue%
atoms_count
(size[, status])¶Get the number of atoms in the residue in size
.
Parameters: | size [integer] :: number of atoms in the residue |
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to CHFL_SUCCESS , you can learn more
about the error by using chfl_last_error . |
chfl_residue%
add_atom
(i[, status])¶Add the atom at index i
in the residue.
Parameters: | i [integer] :: index of the atom to add |
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to CHFL_SUCCESS , you can learn more
about the error by using chfl_last_error . |
chfl_residue%
contains
(i, result[, status])¶Check if the atom at index i
is in the residue, and store the result in
result
.
Parameters: |
|
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to |
chfl_residue%
atoms
(data, natoms[, status])¶Get the list of atoms in the topology in the pre-allocated array data
of size natoms
.
data
size must be passed in the natoms
parameter, and be equal to
the result of chfl_residue%atoms_count()
.
Parameters: |
|
---|---|
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to |
chfl_residue%
free
([status])¶Destroy a residue, and free the associated memory
Options: | status [integer,optional, kind=chfl_status] :: status code of the
operation. If it is not equal to CHFL_SUCCESS , you can learn more
about the error by using chfl_last_error . |
