rotation angles #1592

Closed cherryandmoon closed 3 years ago

cherryandmoon commented 3 years ago

hi, hope this is not a silly question to ask. I am trying to create an angle partition, using angle_part = odl.uniform_partition(0,2 np.pi,393) however, I need anticlockwise angles, i.e., with -2np.pi, but seems not allowed. Would you please give me some advice? Thanks.

ODL enforces strictly increasing angles as a convention, the standard solution if you have real data is to re-order your data to have clockwise angles using e.g. data = data[::-1].

Hi Jonas,

Thanks for your reply. It works.

Best regard, Wenjuan
