Hi,
I'm attempting to use maprot to rotate a map (in order to get the map
covering one molecule in alignment w\ another), and noticed that it seems
to change the contour level of the output map (the new map contoured at 2
sigma seems to be equivalent to the original at 1 sigma).
Based on the example for density cutting, I'm using (cut&paste from csh
script):
maprot wrkin ${inmap} cutout ${outmap} <<eof
mode to
cell xtal ${cell}
grid xtal 100 160 120
symmetry ${symnum}
average
rotate polar 180.0 0.0 180.0
translate 0 0 70.0273
eof
The same effect shows up with the identity transformation (rotate polar 0
0 0 ; translate 0 0 0 ). My best guess is that it's doing some type of
averaging (although removing the average keyword results in error message
"maprot: rcards - wrong number of operaters entered").
Does anyone have any suggestions as to what I'm doing wrong, or
alternative ways of doing this (other than just looking at the transformed
map contoured at 2 sigma)?
Thanks,
Pete
