Fail to transform EPI from Talairach space into MNI space

[dglen]

That apar dataset does not contain the information needed for adwarp. There are other methods to transform between these spaces that are described here:

TT_152_2009c to MNI152_T1_2009c

Neither MNI nor Talairach space is not one specific space, but each corresponds to a kind of family of spaces. MNI has about a dozen popular variants. The Desai atlases were made using AFNI’s @auto_tlrc function by alignment to the TT_N27 space. Consequently, the atlas is the TT_N27 variant of Talairach space. Consider the following options to transform data or coordinates between MNI and Talairach spaces : Affine, 2-piece affine and 12-piece affine transformations to go from generic Talairac…

One of those methods uses the affine+nonlinear alignment between the TT_N27 and the MNI 2009c templates. You can do this yourself, or use the precomputed transformations here and apply it with this command to transform your data. You will have to supply a dataset with appropriate coverage and resolution for the grid in MNI space.
