Feature request:
Would it be possible to add a module to apply a logarithmic transform to
a set of image volumes, like S_out = 100*ln(S_in/S_0) ?
Or add a serial processing function to the ImCalc module, that applies
one formula to a series of images (e.g. prefixing the output filename)?
I keep writing this myself in my batch scripts, but it ought to be
possible in the batch editor, IMHO. It is such a simple thing, but sooo
useful: it allows one to transform absolute signal changes to relative
ones already during preprocessing, so no hassle dividing betas by
baselines to calculate percentage signal change anymore!
(Unless there is anyone who knows of a reason why such transformations
should be avoided. I'm always surprised that I'm the only one in my lab
who does such a thing. On the other hand, I do have some hesitations
when I see people enter unscaled betas into a group level analysis...)
Best,
