External Email - Use Caution        

Hi Yujing,

Thanks. I am wondering about the reason why Freesurfer converts data types to uchar. Doesn't this affect the non-uniformity bias correction that follows? 

Best,

Hi Ruifeng,

 

You can pass -nc (nochange) flag to mri_convert to keep the original data type.

Hi all,

 

My input 001.mgz has data type short, but converted to unsigned byte. The plot shows the intensity of thee two images. How is the data conversion done? Thanks.

 

Best,

Ruifeng
