Dear NiftyRec developers

Unfortunately I get following errors when I run ‘tt_demo_mlem_conebeam’, ‘tt_demo_mlem_parallel’ and 'tt_demo_mlem_parallel_large'. I should mention that I installed NiftyRec (NiftyRec-1.6.8) under Linux, Fedora Core 13 (32 bit) and MATLAB Version 7.6.0.324 (R2008a). I can run the demos of Emission Tomography, successfully, such as et_demo_osem. Please guide me to solve these roblems about transmission tomography. How can I run it

PROBLEM #1
>> tt_demo_mlem_conebeam
??? Undefined function or method 'tt_project_ray_mex' for input arguments of type
'int32'.

Error in ==> tt_demo_mlem_conebeam at 69
p =
tt_project_ray_mex(attenuation,volume_size_mm,source_location_mm,int32(detector_size_pix),detector_size_mm,detector_translation_mm,detector_rotation_rad,ray_step_vox);

PROBLEM #2
>> tt_demo_mlem_parallel
