PDB_READ - Read Protein Database File

PDB_READ is a collection of routines for reading the ATOM records from a Protein Database (PDB) file.

Files you may copy include:

• pdb_read.f90, the source code;
• pdb_read_prb.f90, the calling program;
• pdb_read_prb.out, the sample output.
• 7tln.pdb, a sample PDB file.

The list of routines includes:

• C_CAP capitalizes a single character.
• GET_UNIT returns a free FORTRAN unit number.
• PDB_CHECK truncates the PDB size data to internal maxima, if neccessary.
• PDB_INIT initializes data associated with a given PDB file.
• PDB_PRINT_COORD prints out the COORD array.
• PDB_PRINT_PRTATM prints out the PRTATM array.
• PDB_READ reads the ATOM records in a PDB file.
• PDB_SUMMARY prints a summary of the data read from a PDB file.
• S_EQI is a case insensitive comparison of two strings for equality.
