Attenuation map generated in MATLAB

Hi CASToR users,

I am working on the GATE simulation of phantom and planning to reconstruct an image using the CASToR reconstruction. I also have PET/CT scan of phantom and do have DICOM files. I have generated an attenuation map of the phantom using DICOM images in MATLAB. Then I saved the linear attenuation coefficients (cm^-1) matrix in Matlab binary data file. Now, I am planning to fed this data in CASToR reconstruction along with the GATE output.

I am contacting to know whether this Matlab binary data file format works for the image reconstruction process? Or, do I have to convert it in interfile file format to make it work? Any thoughts on it would be very helpful.

Thank you.
