Matlab is a common tool for post-processing. Matlab command files can be generated using the Tcl scripting language. Using this technique ensures that the same analysis parameters are used.
Here is an example.
# -------------MatlabOutput.tcl-------------------------------------------------------------------
set Xframe 1; # this parameter would be passed in
set fDir "Data/";
file mkdir $fDir; # create directory
set outFileID [open $fDir/DataFrame$Xframe.m w]; # Open output file for writing
puts $outFileID "Xframe($Xframe) = $Xframe;"; # frame ID
puts $outFileID "Hcol($Xframe) = $Hcol;"; # column diameter
puts $outFileID "Lcol($Xframe) = $Lcol;"; # column length
puts $outFileID "Lbeam($Xframe) = $Lbeam;"; # beam length
puts $outFileID "Hbeam($Xframe) = $Hbeam;"; # beam depth
puts $outFileID "Bbeam($Xframe) = $Bbeam;"; # beam width
puts $outFileID "Weight($Xframe) = $Weight;" ; # superstructure weight
close $outFileID
