Dear SPM users I have used the deformations toolbox to do high-dimensional warping. Then I tried to segment the warped images with customized a priori maps. The following error occured: SPM2: spm_segment_ui (v2.4) 14:26:56 - 03/11/2005 ======================================================================= * - SPM2: spm_vol ------------------------------------------------- Error reading information on: ..\apriori\sAN1792_gray_DeformationTx.img Please check that it is in the correct format. What is excately mean with format? The warped images and the a priori maps differ in Dimensions Voxel size Origin What I have to change in order it works?
