Borg_Error for large t (4th dimension) nii.gz files in Windows

[dicemt]

I have encountered a display/load error (_BorgError) for large 4D nii.gz files in Windows. Although I still cannot figure out the exact situations that lead to this error, I have seen the latest MRIcroGL (1.2.20220720) sometimes fails to load large t (4th dimension) nii.gz files and shows _BorgError.

Some (marginal) info:

• The older 1.2.20211006 version has no Borg_Error issues in the same environments.
• If I converted them to uncompressed NIfTI files (*.nii), MRIcroGL displayed them without any issues.
• Large t (4th dim) is not always critical. Not found Borg_Error for HCPpipeline preprocessed nii.gz files (4th dim > 1000)
• (At the moment) I have not seen any issues in small t files (4th dim < 50).
• No issues in 3D volumes (4th dim = 1).
• Modality (function or diffusion) does not matter.

Can you re-download and test the latest release it will now report version 1.2.20220720c. If this works for you, I can refresh downloads on NITRC.

Thank you so much for the fix! Borg_Error is gone, and now I can load/display large nii.gz files!
