This is MullPoP, a program to carry out a Mulliken Population 
Analysis that complements the Mulliken Analysis supplied by 
Gaussian 98 using pop(full). MullPop provides the gross MO 
population in terms of both AOs and atoms. Further, it gives 
the atomic charges that can be compared with those provided 
in the G98 output as a reliability test. 

A makefile is provided with the sources, so you only have to type 
"make" to build the executable. I test the program in my 
RedHat 7.2 Linux machine under gcc 3.0.2. The program was written
in very plain C so I guess it should run on almost every system. 
In any case, you should make the corresponding changes to the 
makefile.

MullPop is able to read the Gaussian 98 output and extract the
relevant information. It sends to the screen some useful messages
concerning the G98 output processing and then generates the 
MullPop.log file which contains the population analysis.

MullPop is invoked as simply as "MullPop <your_g98_output".

Note that you should include both the pop(full) and
iop(3/33=1) keywords in your G98 input to print the overlap and
coefficient matrixes.

There are no restrictions on matrix dimensions since the program
uses pointers and memory is allocated on the fly. 

I've considered several possibilities concerning the nomenclature
for basis sets used by Gaussian 98, but this might not be exhaustive.
Thus, if you find some strange format in your MullPop.log file and 
the "normal termination" message appears on the screen, you are using 
a basis set that I didn't considered. In this case, send me your G98 
output and I'll fix the problem.  

Don't hesitate to contact me if you find any other problem. Enjoy!!
