arindam,
There are a couple of ways to do this ... one would be to use the FFT module which will pick up the graph paper as a very regular repeating pattern and allow you to mask that signal out.
Another way is to use a combination of filters to just threshold the graph paper out as it is slightly grayer than the ecg signal. We've included a robofile on how this can be accomplished and also how to smooth the signal out a bit. Note that RR operates on white pixels so we switch to the negative of the image during this process in order to focus on just the ecg pixels.
Yes, you can use TIFF images in RR ... you just cannot post them in this forum as most browsers do not support TIFF display.
STeven.
