[ESPResSo-devel] Doubt in an analysis TCL script provided with Espresso

[prateeksha s]

Hi,

I am developing using Espresso code, and I'm converting the fluctuations.tcl script, found in packages/mbtools/analysis/, to C. I encountered this piece of TCL which I do not understand, hence, I'm unable to translate it to C. 

The difficult-to-understand code is in italics : 
set re [expr [lindex [lindex $rawmodes 1 $i $j] 0]*$norm]
set im [expr [lindex [lindex $rawmodes 1 $i $j] 1]*$norm]

rawmodes is a 2D array( or is it? ) so trying rawmodes[1][i][j][0] just doesn't make sense. 
Can somebody please clarify.

Thanks and regards,
Prateeksha
