I should have been more explicit. Yes, it is the number of columns that
needs increasing. CAD is being used to iteratively combine groups of mtz
files into one large file with more that 20 data sets.
Here is the problem: One has several native data sets and over 20 data
sets from different ligand complexes. Unfortunately all are somewhat
non-isomorphous. Which pairs of data sets would give the best difference
maps in analyzing the ligand complexes?
The problem appears to have been solved with the help of Jimin Wang
here. We switched to version 4 where scaleit now is formatted for 14 (!)
columns for each data set. Changes in NDER, MCOLS, Maxsets, NLPRGI and
column labels data lists (COLLAB) had to be made in scaleit. But the
final matrices of cross-differences are giving the desired information.
If anyone wants the edited version of scaleit, please let me know.
