I CANT BE SURE of what has happened BUT maprot is a very complicated
procedure and your script is trying to do 2 things at once - change the
cell and apply the mask.
I would try changing the cell first, then generating the mask, then
applying it
or else: generate mask, apply mask, then change cell.
But at every stage look at the result! ( mapslicer or coot or whatever)
to make sure you have really achieved what you are aiming for!

Hi all,
I am trying to cut density from EM map (in a small P1 cell) into big P1 cell
for MR.
The mask is defined by a certain cut-off level in mapmask :
mapmask \
mapin em.map \
mskout em.msk << eof
MASK CUT 353
MODE mapin
eof
I use maprot to cut the density to the big P1 (that has the same grid
spacing as the original small P1).
maprot wrkin em.map mskin em.msk mapout cut.map << eof
MODE TO
CELL XTAL 1098. 1098. 1098. 90. 90. 90.
GRID XTAL 375 375 375
SYMM P1
AVER 1
ROTA EULER 0.0 0.0 0.0
TRANS 0.0 0.0 0.0
END
eof
When cut.map is read by mapmask the program reports that the minimum of the
map is -310.
How come the minimum is not the cut-off level used to define the mask ? What
am I missing/Doing wrong ?
Many thanks in advance for all suggestions and comments,
Peter.
