QCMP125. DISMAP: A DOS Program to Graphically Display
Distance Maps of Molecules
by Brian T. Luke, IBM Kingston, Neighborhood Road,
Kingston, New York 12401
DISMAP is a program that reads both the structure of a
molecule from a disk file in Protein Data Bank (PDB)
format, and graphically displays the distance map. The
user has the option of:
1. Modifying the distance ranges used to generate
the map.
2. Selecting only some of the atoms in the
structure to include in the map. This selection is
by atom and/or residue label.
3. Generating either monochrome or color
PostScript files which can be sent to an
appropriate printer.
DISMAP is distributed with both a source file,
"dismap.f", and an executable file, "dismap.exe", that
contains the virtual memory manager and the plot
functions developed by Silicon Valley Software. The
program first reads a data file that tells the program
what the display type is (e.g., Hercules Monochrome,
CGA 4-Color, VGA 16-Color, etc.) and certain other
parameters that control the location of the plot on the
terminal.The purpose is to provide as much
flexibility as possible without having to recompile the
program. This data file also contains information that
controls the generation of PostScript files that
contain the current display. Hardcopy is generated by
simply sending these files to a PostScript printer.
Due to the requirements of the program and compiler,
DISMAP will only run on a 386-class Personal Computer,
or higher, with 8M or more of memory and graphics
display.
