Hi Gonzalo,

FS_RESCALE_DICOM is set through environment variable.

1. if you are using bash, export FS_RESCALE_DICOM=0 2. if you are using tsch, set FS_RESCALE_DICOM=0

Best,

Yujing

External Email - Use Caution Hi:

I am trying to convert CT images from DICOM to MGZ using mri_convert. When running it shows the message "INFO: applying rescale intercept and slope based on (0028,1052) (0028,1053). If you do not want this, then set FS_RESCALE_DICOM to 0 and rerun."

Where can I find the FS_RESCALE_DICOM option ?

Sincerely,

Gonzalo Rojas Costa
