README

Here, we present an extension to our previously published structural ultrahigh resolution T1-weighted magnetic resonance imaging (MRI) dataset with an isotropic resolution of 250 µm (https://www.nature.com/articles/sdata201732), consisting of multiple additional ultrahigh resolution contrasts. Included are up to 150 µm Time-of-Flight angiography, an updated 250 µm structural T1-weighted reconstruc-tion, 330 µm quantitative susceptibility mapping, up to 450 µm structural T2-weighted imag-ing, 700 µm T1-weighted back-to-back scans, 800 µm diffusion tensor imaging, one hour continuous resting-state functional MRI with an isotropic spatial resolution of 1.8 mm as well as more than 120 other structural T1-weighted volumes together with multiple corresponding proton density weighted acquisitions collected over ten years. All data are from the same participant and were acquired on the same 7 T scanner. The repository contains the unprocessed data as well as (pre-)processing results. The data were acquired in multiple studies with individual goals. This is a unique and comprehensive collection comprising a “human phantom” dataset. Therefore, we compiled, processed, and structured the data, making them publicly available for further investigation.

Dear Dr. Luesebrink,
Congratulations on this towering achievement. The quality of pictures is simply astounding. However I've run into issue when opening "sub-yv98_ses-3777_T2w_registered_to_T1_250um_orignial.nii.gz" and "sub-yv98_ses-3943_ToF-150um_registered_to_T1_250um_original.nii.gz" files. When trying to unpack them, I get "unexpected end of archive" error. Is it somehow possible to fix this error?
Thank you for your work.

Hi,

I'm sorry for the trouble. It seems the upload was incomplete of both files. I'll update as soon as possible - probably beginning of next week. In the meantime, you can download these files from a mirror: https://doi.org/10.24352/ub.ovgu-2020-145

On the left you can find "Ultrahigh resolution multi-contrast data registered to the 250 µm data. (15.09Gb)" which includes all data registered to the 250 µm data.

Best,
Falk

Hi,

the files should updated. Thanks for making me aware of this!

There will be a minor update soon as the day of acquisition was not included in the JSON files. That may be of interest for longitudinal analysis of the data.

Best,
Falk
