Zahir,
Your data will need to be in the form of 25x256x256x17 (in the case of the
25 channel data set). Is your data in a single series? To make sure
BioTensor is reading your data in correctly, can you do the following:
* Start SCIRun by typing "./scirun" at the command line
* Select a Teem->DataIO->DicomToNrrd module
* Click on the UI button and read in your data the same way you did for
BioTensor.
* Select a Teem->NrrdData->NrrdInfo module.
* Connect the output port of the DicomToNrrd and the input port
of theNrrdInfo module by clicking the middle mouse button on the
DicomToNrrd output port and dragging the mouse to the input port of
the NrrdInfo module.
* Right click on the NrrdInfo module and select "Execute"
* Open up the NrrdInfo interface by clickin on the UI button.
Please let me know what it says for each Nrrd axis in the NrrdInfo module.
