Hi Jie,
it should be ok. We typically don't recommend this type of "french fry" voxel with one dimension beting almost 4 times as long as the others. You are usually better off getting closer to isotropic. That said, if the SNR is good enough try giving it to recon-all. One thing to be wary of though is the orientation. Do you have a .mat file to go with the .hdr/.img? Otherwise you won't be able to tell left from right. Can you get them in some other format, such as nifti?
cheers Bruce

I am using recon-all command to process some analyze images. But it seems that this command does not work for all .img images. For example, I have an image with the following information:
256x256x124 0.7mm x 0.7mm x 1.5mm data type: uint8 description: position:0 0 0 file orientation: 1 0 0 0 1 0 0 0 1
working orientation: 1 0 0 0 1 0 0 0 1
Will the dimension, resolution, and data type all matter in the process?
