Dear Frank,

I would like to ask about import anatomic image. When I open [Slices][Insert Other Images] and I choose my image (.dcm format) it crashs. When I choose (.nii) format-it looks like (in attachment) it is shifted:

Sorry about the bug. Could you upload a sample dataset? I will fix it.

Hi Gabriela,

    It seems to me that the SRC file was created from de-identified DICOMs (please correct me if wrong), and somehow the deidentifying process caused DSI Studio to get the wrong spatial resolution.

    The data were acquired at 2mmx2mm in-plane and 3-mm slice thickness, but the SRC wrongly shows 3x3mm in-plane.

    To solve this issue:

(1) Click [Step T2][Reconstruction] open __M039Y_RP_s22.src.gz
(2) Set [Step T2][Edit][Overwrite Voxel Size]=2 2 3
(3) Click [Step T2b][Run reconstruction]

    If your DICOM has been de-identified, then you may consider using another de-identification tool. 

    If your DICOM has not been de-identified, it is likely there is another problem, and you may send me the DICOM (if possible), and I will fix the bug.

Best,
Frank
