    Hi again,

    Thanks to the people mailed in suggestions for the REFMAC
    no associated file name error. The solution below is from Garib:


> That is exactly why I asked log file. I guess number of atoms is 40001. Limit
> for maximum number of atoms is 40000.
> If you have low res use MAKE HYDRogens NO.
> Or you change MAXATOM in atom_com.fh to higher value and QQA in the
> pls_incl.fh to the same value. Remove all *.o
> and compile again. Then problem will go away. We will give sensible message
> for the next version.
