Hi,

I am trying to make a simple movie with the vmdmovie maker on my SGI
station with the following options
movie type: rotation about Y axis
number of frames to render: 5
Rendering method: Snapshot (screen capture)
Pre-compression processing steps: none
Movie compression format: AVI (SGIdmconvert)

The program generates the rgb files but fails to generate the ppm ones.
Here is part of the output:

Info) Rendering complete.
Info) Rendering current scene to
'/stor/ioana/ions_waterbox/KCl_roty.0003.rgb'..
Info) Rendering complete.
Info) Rendering current scene to
'/stor/ioana/ions_waterbox/KCl_roty.0004.rgb'..
Info) Rendering complete.
Converting frames from rgb format to ppm... Converting frames to AVI video
format dmconvert -v -f avi -p video,comp=jpeg,brate=8000000,rate=24 -n
/stor/ioana/ions_waterbox/KCl_roty.####.ppm,start=0,end=4,step=1
/stor/ioana/ions_waterbox/KCl_roty.####.ppm
/stor/ioana/ions_waterbox/KCl_roty.avi

Error:------------Scanning input...
child killed: bus error
(a core is dumped)

I am guessing that the problem is that vmd can not find dmconvert on my
station as it is in a different directory (/usr/sbin/dmconvert) than those
showing in the path

puts $auto_path /usr/local/vmd/vmd_1.8/scripts/tcl
/usr/local/vmd/vmd_1.8/scripts ./lib /usr/local/lib
/usr/local/vmd/vmd_1.8/scripts/tk8.3 /usr/local/vmd/vmd_1.8/scripts/vmd
/usr/local/vmd/vmd_1.8/plugins/IRIX6/tcl
/usr/local/vmd/vmd_1.8/plugins/noarch/tcl

(although the directory shows up in the path in my .cshrc file)

Also I try to use Image smoothing I get an error saying
Error: could not execute: "pnmsmooth": no such file or directory
Same with rescaling ...

Could you please advise how I could correct this?

Thanks,
Ioana
