Dear Sir,- that all of the input files have the correct dimensions , is it necessary that dimensions of all functional and structural files should be same ?The Dimensions of all structural files issizeof_hdr 348data_type FLOAT32dim0 3dim1 160dim2 256dim3 256dim4 1dim5 1dim6 1dim7 1vox_units mmtime_units sdatatype 16nbyper 4bitpix 32pixdim0 0.000000pixdim1 1.000000pixdim2 1.000000pixdim3 1.000000pixdim4 1.000000pixdim5 0.000000pixdim6 0.000000pixdim7 0.000000vox_offset 352Dimensions of all Functional filessizeof_hdr 348data_type INT16dim0 4dim1 64dim2 64dim3 46dim4 300dim5 1dim6 1dim7 1vox_units mmtime_units sdatatype 4nbyper 2bitpix 16pixdim0 0.000000pixdim1 3.000000pixdim2 3.000000pixdim3 3.000000pixdim4 2.500000pixdim5 1.000000pixdim6 0.253332pixdim7 47455.246094vox_offset 352cal_max 0.0000cal_min 0.0000scl_slope 1.000000scl_inter 0.000000phase_dim 0freq_dim 0slice_dim 3slice_name alternating_increasing_2slice_code 5slice_start 0slice_end 45slice_duration 0.000000time_offset 0.000000intent Unknownintent_code 0intent_nameintent_p1 0.000000intent_p2 0.000000intent_p3 0.000000qform_name Scanner Anatqform_code 1On Thu, Feb 20, 2020 at 10:26 AM paul mccarthy <[log in to unmask]> wrote:Hi Vasudev,As I said in your other thread, this is due to a poor registration. Double check the following:- that all of the input files have the correct dimensions- The structural brain extraction is good- The func-struc registration is good- The struc-standard registration is good- The process you used to generatehighres2standard_warp_inv

applywarp -i Visual_thr_mask.nii.gz -r reg/example_func.nii.gz -o Visual_func
--postmat=reg/highres2example_func.mat -w reg/highres2standard_warp_inv
I dont understand what is the problem with my approach-could you please provide
me some input.
