Leipzig: Correction of L/R Discrepancy Posted By: Maarten Mennes - Mar 19, 2010Tool/Resource: 1000 Functional Connectomes Project As reported earlier, users of the Leipzig data indicated there might be a discrepancy between the L/R orientation of the Leipzig anatomical and resting-state data. Together with the Leipzig PI we were able to trace this issue to a slight difference in the processing path after image acquisition. The subjects that were affected by this issue could be identified and L/R flipping their anatomical scans resolved the issue. As of today, MARCH 19 2010, we replaced the Leipzig dataset with the correct one. Below is a list of the subjects that were affected by this issue. If you downloaded the dataset a long time ago you might prefer L/R flipping the mprage_skullstripped.nii.gz image using the following commands and reprocessing only those subjects. Commands: 3drefit –orient LPI mprage_skullstripped.nii.gz 3dresample –orient RPI –prefix temp.nii.gz –inset mprage_skullstripped.nii.gz mv temp.nii.gz mprage_skullstripped.nii.gz IF YOU HAVE ANY DOUBT ABOUT THE CORRECTNESS OF YOUR LEIPZIG DATA, we suggest downloading the dataset again and processing it from scratch. That way you are sure to have the correct data. We apologize for this inconvenience, but strive to have to most correct data available for you to use. As always, we appreciate any input on the project and data.
