Hi Chao,
It's a bug.  The first findclash closes the output file (standard output) so all the subsequent findclashes fail.  I've fixed it in the code now and the fix will be in tomorrow's daily build.  It's not too big a change so you might want to just edit the file with the bug yourself.  The file is :  <your Chimera installation>/share/DetectClash/__init__.py .  On line 294 change:

outFile.close()

to:

import sys
if fileName != sys.stdout:
outFile.close()

Hi, folks!
I came across with a problem when using
chimera --nogui file.cmd > data.log

the file.cmd is as follows:

open /home/lynn/project/hivrt_pdb/holo_without_mutation/1C1C.pdb
findclash :.het@C1 overlap -1 hbond 0 ignoreIntraRes true log true
findclash :.het@C2 overlap -1 hbond 0 ignoreIntraRes true log true
findclash :.het@C3 overlap -1 hbond 0 ignoreIntraRes true log true
findclash :.het@C4 overlap -1 hbond 0 ignoreIntraRes true log true
findclash :.het@C5 overlap -1 hbond 0 ignoreIntraRes true log true
findclash :.het@C6 overlap -1 hbond 0 ignoreIntraRes true log true

If i use the graphic version and read the cmd file, it worked quite well and I can find all I need in the reply log.
But when it came to the nogui version, the data file only contains the result of the first two lines of the cmd file. That is

open /home/lynn/project/hivrt_pdb/holo_without_mutation/1C1C.pdb
findclash :.het@C1 overlap -1 hbond 0 ignoreIntraRes true log true


Results are:
Opening 1C1C.pdb...
1 model opened
Opened 1C1C.pdb containing 1 model, 7997 atoms, and 1096 residues
Allowed overlap: -1
H-bond overlap reduction: 0
Ignore overlap between atoms separated by 4 bonds or less
Ignore intra-residue overlaps

5 overlaps
atom1  atom2  overlap  distance
#0:999.het@C1  #0:100.A@CD1  -0.352  4.112
#0:999.het@C1  #0:100.A@CD2  -0.643  4.403
#0:999.het@C1  #0:188.A@CD2  -0.723  4.363
#0:999.het@C1  #0:188.A@CB   -0.883  4.643
#0:999.het@C1  #0:188.A@CG   -0.989  4.479









Error in the shell is as follows:

$ /usr/local/chimera/bin/chimera --nogui /home/lynn/cmd/1C1C.cmd > /home/lynn/project/data/distance/1C1C.dist
Traceback (most recent call last):

Could anyone give me hand? I am really frustrated! Thanks in advance...
