fitmap search error

[Elaine Meng]

Maybe this map file is bad somehow. I assigned symmetry and wrote it out from Chimera1. I didn't have this problem with other maps, e.g. from molmap.

If I open the attached map (D2 symmetry) and then use commands

vol #1 level .008 color 50,50,50,50
open 1gcn
fit #2 in #1 search 5

Log says:
fitmap #2 inMap #1 search 5

I guess it happens with any map that has a symmetry assignment. I successfully used search with a molmap map and then in ChimeraX assigned some symmetry to that map and then tried again, which failed with the error reported above.

Fixed.

I had not tested fit search using a map with symmetry assigned. Fit search uses the symmetry to eliminate symmetrically equivalent fit results.
