i am not able out find out why my mcf file is not generating .

Traceback (most recent call last):
File "./mcfgen.py", line 1558, in <module>
readNative(ffFile, atomParms)
File "./mcfgen.py", line 1020, in readNative
scaling_1_4 = float(line.split()[1])
IndexError: list index out of range

Hello shub!

Please check the format of the intramolecular section in your *.ff file. If this doesn't work, can you please upload your *.ff files?

thanks for your reply!the problem is sorted out ....the mcf file got generated.but now the the inputfile is showing some error.when i check the log file its showing Start type
********************************************************************************

You have 'read config' (with a space) under Start_Type in your input file. What you want is 'read_config' (with an underscore).

You will also need to tell Cassandra how many molecules of each species are in your starting xyz file. For example,

read_config 100 100 300K.inp.xyz

You have a blank line after specifying translation probability. Try deleting the space and let us know if that works. You may also want to delete the blank line immediately following # Prob_Rotation keyword.
