Hi,

I'm using the Tcl script rotation_movie.tcl which, at the moment, renders
images as bmps (i.e. as snapshots). I'd like to change this to rendering to
tga with the Tachyon internal option in VMD. I've tried different approaches
to change the Tcl script but still can't get the output files to be in tga
format. I'm getting error messages each time, e.g. "invalid render method
'TachyonInternal"

Using the original rotation_movie.tcl, which is:

proc make_rotation_movie_files {} {
        set frame 0
        for {set i 0} {$i < 360} {incr i 20} {
                set filename snap.[format "%04d" $frame].rgb
                render snapshot $filename
                incr frame
                rotate y by 20
        }
}

I've changed lines 4 and 5 to render in tga (using the Tachyon Internal
option in VMD): But this doesn't work..

proc make_rotation_movie_files {} {
        set frame 0
        for {set i 0} {$i < 360} {incr i 10} {
                set filename snap.[format "%04d" $frame].tga
                render TachyonInternal $filename
                incr frame
                rotate y by 10
        }
}

Please can anyone help? Many thanks in advance,
Yalini.
