1. First, you have to register as a new user, or log into the system if you have already registered.
2. Second, upload your compressed anonymized raw T1w/T2w brain MRI data in NIFTI format. Only Zip compression format is accepted. Most of MRI scanners produce DICOM data so a conversion to NIFTI format is required. There are many software packages that can do the job, but we recommend dcm2nii (part of MRICRON software), which is a free and reliable tool. Due to large amount of submissions, our server is overburden. To process large amount of data, please first contact li_wang@med.unc.edu and gang_li@med.unc.edu. We are looking for collaboration. You must upload an anonymized and compressed zip file. We recommend to submit both T1w and T2w raw images, for a better tissue segmentation.
4. Finally, you will receive an e-mail informing about your request completion. The report will be included as an attachment, and you will be able to download a package including image files generated during the process. If you have not received any results within 1 week, please kindly let us know. Sorry that there might be some delay due to submission peaks. 5. If you have large number of subjects, here is the second option by directly sending li_wang@med.unc.edu a download link: Please organize the file structure like this (case-sensitive): Month-3/ protocol.txt subject-1-T1w.nii subject-1-T2w.nii ...
Month-6/ protocol.txt subject-4-T1w.nii subject-4-T2w.nii ... Basically, put the subjects with similar ages into one folder, like Month-3 means 3-months subjects. protocol.txt should be your imaging parameters: Scanner, ?T, TR/TE/TI. To help our fast processing, please make sure the file names are unique across all months folders. |
