Dear all,

I was trying to calculate the volume of a protein, I used the following codes:

scalar wmain = radius

scalar wmain mult 0.85

scalar wmain add 1.4

coor volume space 660000 select segid prot end

set MV = ?volume

But, I got the following errors:

***** LEVEL -1 WARNING FROM *****

***** MUST FILL SCALAR ARRAYS TO USE

******************************************

BOMLEV ( -2) IS NOT REACHED. WRNLEV IS 5

CHARMM> set MV = ?volume

RDCMND: can not substitute energy "?VOLUME"

Parameter: MV <- "?VOLUME"

Since I can't find any help in corman.doc, could anybody please help me fix it?

Thanks in advance!
