Hi,

I'm trying to align two large 3d+time datasets recorded on different days, and as one step I thought I needed to upsample them so make the addition smoother. But 3dresample refuses work with the message

r frdg: alloc failure: 21073920 bytes!
failure to resample dataset, exiting...

Is that a limitation of 3dresample, a problem on my system or am I doing something wrong?

The command line I used is

3dresample -dxyz 1 1 1 -prefix f1-5.fine -infile f1-5+orig




Incidentally, is this the right/best way to go about combining two different scan sessions:

- aligning anatomicals of E2 to anatomicals of E1 using 3dvolreg
- upsampling E1 functionals using 3dresample
- aligning expt 2 functionals to expt 1 functionals using 3drotate with usampled E1 functionals as gridparent and E2aligned as rotparent
- concatenating the sets

Thanks for any insight,
Kai
