Questions about understanding QCreport
Dear all,
After I run DTIprep, i don't understand some points in QCReport.
1. Some parameters are blank under "Interlace-wise Check Artifacts"and "Inter-gradient check Artifacts", as following:
Interlace-wise Check Artifacts:
Gradient#: AngleX AngleY AngleZ TranslationX TranslationY TranslationZ Metric(MI) Correlation
Inter-gradient check Artifacts:
Gradient#: AngleX AngleY AngleZ TranslationX TranslationY TranslationZ Metric(MI)
Whether there should be parameters following Anglex, et al.
2. As I seen in the QCReport, there are results of "EddyCurrentHeadMotionCorrectIowa ...
Transforms"whether that is mean the QC check has done the eddy current and head motion correction. If so how to understand the following results?
I don't understand why each included gradient has two lines, one is parameters, and the other is fixed parameters. And why the following numbers have different number, since "parameter" has 12 numbers, but "fixed parameters" has 3 numbers?
0 - Parameters: [0.9997539562179837, -0.0000456712971941987, 0.00012814643209806194, 0.0001919390366571939, 0.9996859054763518, -0.00002926969037700233, -0.00011713357421570307, 0.00010946833467130879, 0.9997676269027517, -0.0009163895499214427, -0.005300804295234882, 0.008665774469949795]
0 - Fixed Parameters: [2.0063291738889677, 29.472202481645756, -25.351412463387636]
1 - Parameters: [0.9973658126577162, -0.0032099643661705193, -0.0026982670174528984, 0.003487339476547441, 0.99321195724164, 0.011081261533761417, 0.0035208460196087398, -0.009190952090957454, 0.999104607135376, 0.06964221564603196, -0.28415220872622377, -0.7374703184740822]
1 - Fixed Parameters: [2.0063291738889677, 29.472202481645756, -25.351412463387636]
3. when we need to transfer nerd files to nil format, we should transfer the *.nrrd or *_QCed.nrrd? It seems I can only transfer *.nrrd to nil, and failed to transfer *_QCed.nrrd to nil.
Thank you so much for your help.
