Hi all,

I'm trying to get Fc from EM map for the use of MR search model.
The EM map is now in the P1 cell which has 64 grid points on each axes, and is 
in the box [-32 to 31, -32 to 31, -32 to 31].
When I tried SFALL to get Fc from this map, the SFALL compained as below in the 
last part of the logfile.

 Check map header agrees with fixed requirements for SFcalc for this  
spacegroup.
 Check KV1 KV2 KU1 KU2 Ksec,Msec - IXmin IXmax..
      -32  31   -32  31   -32  64        0  63     0  63     0  63

 SFALL:   **** Fatal disagreement between input info and map header

It looks to me that my map should be located in the [0 63, 0 63, 0 63] which is 
an asu defined in SFALL.
The manual of SFALL also looks like indicating this point.

The EM density has a shape of a triangular disk whose center is located in the 
origin of the coordiates system.
How can I move this density into the box [0 63, 0 63, 0 63] and update map 
header  information accordingly so that SFALL can read my density ?

Thanks in advance.

JK
