error in Box-Cox transformation

[knutj]

When I use Box-Cox transformation I get this error.

Traceback (most recent call last):
File "/home/knutjb/pymediator/bin/tm_tools", line 164, in

nibabel.deprecator.ExpiredDeprecationError: get_affine method is deprecated.
Please use the img.affine property instead.

• deprecated from version: 2.1
  After updating to img,affine

There has been an update to Nibabel. I am using Python 3.7.

It caused by using a deprecated function in Nibabel.
