It is important to read these instructions to properly set up the DATMEMFC file and the data file to run in the MEMFCS program. This is the “data” file to input the correlation function data set from a FCS run. This DATMEMFC file is the file to input parameters for using MEMFCS on a Windows XP computer. The MEMFCS program is gifted by Dr. S. Maiti. Acknowledgements are required when publishing data from this program.
