Can you send your commandline with --interp as well as the terminal output?

Well, there is no difference between trilin or nearest. mri_vol2surf displays segfault regardless which option I use (trilin or nearest).

I don't understand what the question is. If you need to interpolate, then use --interp trilinear doug

Allright! The only point I would like to emphasize is:
Regardless if option trilin or nearest is used I need to interpolate the functional data to the structural image of the subject. This might be due to a feature of the function "build_sample_array" in the "mri_vol2surf" source code. In this function there are some constant values (din = 1.0, dout = 0.1, nsamples = 10), which might be the reason why I need to interpolate the functional data to the structural image. Currently I can not investigate the code any further. Do you have enough experience with the source code to clarify this question?

You can use --projfrac (which can perform an interpolation with --interp trilinear)

Sorry for this question, but now I am confused. Do you mean that I should not use projopt and just use the interpolation? If so why should I not use projfrac?

You'll have to do without it for now and just do the interpolation
