set isForceStackSameSeries to 1 (freesurfer#904)
Browse files Browse the repository at this point in the history 
* 1. check in package dcm2niix
2. add DICOMRead3/niiRead3 to convert dicom using dcm2niix
3. fix dcmGetDWIParams() to use stricmp() to compare the Manufacturer tag

* set TI to -1 when there is no TI in dicom file for MGH_FREESURFER

* remove unused codes

* This is the correct version.

* redo the check in

* For some unknown reasons, dcm2niix and dcm2niixfsexe executables failed linking in nightly builds.
They are excluded from the build until we figure out why.
libdcm2niixfs.a is renamed to libdcm2niix.a

* 1. rename dcm2fsWrapper.h => dcm2niix_fswrapper.h, dcm2fsWrapper.cpp => dcm2niix_fswrapper.cpp
2. add comments to dcm2niix changes

* fix bvecs

* 1. introduced new type MRI_USHRT (10) - unsigned short,
   convert DT_UINT16 to MRI_USHRT, MRI_USHRT to DT_UINT16
2. added macro MRIUSseq_vox & MRIUSvox to access voxel in pre-allocated memory
3. added handling of type MRI_USHRT in various functions
4. introduced environment variable FS_MGZIO_USEVOXELBUF to read/write (mgzRead/mgzWrite)
   voxels in one buffer access. FS_MGZIO_USEVOXELBUF is ignored if mri voxel buffer is
   not allocated as a big chunk.
5. introduced environment variable FS_MGZIO_TIMING to time voxel read/write in mgzRead/mgzWrite

* ignore FS_MGZIO_USEVOXELBUF if mri voxel buffer is not allocated as a big chunk

* add dcm2niix license.txt

* license files for dcm2niix - license.dcm2niix.txt and license.charls.txt

* 1. set isForceStackSameSeries = 1 in dcm2niix_fswrapper (dcm2niix command line option - '-m y' merge 2D slice)
2. print messages for slices stacked
