CT Dicom to mat HU display problem

I ran CERR on CT dicom files to create one mat file that has a variable planC containing the image data. I then took planC (a 1x25 cell) with code imagesc(CTimgmat(:,:,200)) to display the image and compared the x,y,index position/value to that which is displayed for the dicom images in OSIRIX or any other viewer that displays the pixels in HU units. The two didn't match up by about a thousand but it differs pixel to pixel. My goal is to run imagesc(CTimgmat(:,:,"slice#")) and have index # display as HU. Can anyone help?

Did your conversion take the slope and intercept in the dicom info into account?

I've tried multiple solutions listed below, but nothing ever matches up to the HU listed in Osirix
The people on github seem experienced with both CERR and Matlab, so I suspect the best course of action is to continue on that thread. I don't know why it would match up with OsiriX if you are using the dicom fields to convert to HU.
