Hi Francesco, From the traceback you provided it seems that when you start the MD Movie tool and specify your input files, you are selecting something other than "Amber" from the "Trajectory format" menu. Perhaps you aren't changing that menu at all and are leaving it on some choice other than "Amber". To use a prmtop/mdcrd you need to change that menu to "Amber"! The traceback is from an error in the DCD-reading code, which is only used for formats other than Amber. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Jan 3, 2011, at 9:01 AM, Francesco Pietra wrote:
hello: While I have solved how to show chloride ligands in case of allh protein, the movie still fails in my hands.
I have installed the daily built

getting the same error on prmtop/inpcrd:

for files that are correctly handled by VMD (I have also tried prmtop/inpcrd files that were correctly handled by chimera a couple of years ago, getting now the same 'out of index error'. As the other files for a would-be-publication have already been prepared with chimera, I would like to solve the issue for the remaining figures.
Thanks

Hello: Two not new questions.
(1) I am trying to read prmtop/mdcrd files from Amber MD with chimera alpha version 1.5 (build 30702) 2010-06-10 23:51:24 GMT, getting "index out of range" (the files are correct, they open with VMD)

(2) Although I suppose I used in the past ATOM ATTRIBUTES to display chloride anion at its standard radius in preparing figures for publication, I just get it now as a tiny dot as set by MODELLER. That with proteins without or with non-polar hydrogens.
For example
TER 6750 LYS A 426 ATOM 6751 Cl- Cl- A 427 -31.021 4.748 41.205 1.00 6.32 Cl TER 6752 Cl- A 427 ATOM 6753 N LEU B 1 -13.959 20.979 -35.226 1.00 63.95 N
I can't remember how to specify the chloride radius in command
sel :427@Cl-
************************************************
Thanks for pointing me to the correct procedure
