Dear Jayaraman T,
You can turn off helical correction and mass weighting using command options, for example with this command:
define axis perHelix true helicalCorrection false massWeighting false
I’m just trying to convince you this is the easy way!
However, you already also have the source code in your download, as Eric described in his reply:

You can script it with Chimera commands “define” to create helix axes cylinders and “angle” to measure the angle between any pair of those.

Since we are interested to calculate the interhelical angle and axes for a set of proteins, we found Chimera is really helpful for getting us the results. And i would like to do certain analysis on the basis of these interhelical angles, so i kindly request you to provide me the source code and other requirements for calculating the angle between helices. It would be grateful to you and please help me out at your earliest convenience.
