Strange error related to dark image scan with x2 gain about csxtools

[ambarb]

Can load the raw x1 gain dark images.

-used with the above code

stack = get_fastccd_images(bgnd1, (None), flat=None)
print(type(stack))
#images = get_images_to_3D(stack) 
images = stack[0]
print(images.shape)

Can NOT load the raw x2 gain dark images.

-used with the above code

stack = get_fastccd_images(bgnd2, (None), flat=None)
print(type(stack))
#images = get_images_to_3D(stack) 
images = stack[0]
print(images.shape)

So need to try to load from file directly not using get_fccd_images() to understand if something bad happened to this file.

[ambarb]

probably bad file or data is missing and databroker refuses to open
