Are you working with a full node list?
In general, it seems like working with surface data takes up a huge amount of memory because of the size of the files that result from working with a full node list. It also seems as if you need a full node list for some things (3dmaskave) to work, but not for others (surfsmooth and maybe 3ddeconvolve, i am not sure).
would it be possible to get a script that would take 1D files that aren't a fullnode list and create one, say given the surfaces that were used to create the current file, or even just a complete node list? this seems like it would make a lot of this surface stuff easier.
Thanks,
Stephanie
