Dear Uttam, > can't find package Itk > while executing > "package require Itk
the problem is related to the Itk package and there are two possibilties: 1. You have the Itk 4.0.1 version installed, in this case there are some issues, and I suggest you revert to the previous version ( tcl-itk-3.3.2) 2. You don't have the tcl-itk package in that case please install tcl-itk-3.3.2 version. https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Ftcl-itk%2Ftcl-itk-3.3-2&grep=itk For further information see thread on this forum (from a while ago): https://www.mail-archive.com/pw_forum@pwscf.org/msg30957.html Hope this helps.
