mmrotate supported angles

[imadgohar]

the annotation tool I used can rotate in both clockwise and counter clockwise manner, I followed the convention to rotate all the boxes in clockwise fashion so the largest radian I got is 3.1 which is less than 180 degree. My angle range is now 0 to 180 degree with no negative number.

I trained a model with angle version (le90) but it is unable to detect objects having theta>90 degree.
as angle[-90,90] = [0 90 180] but theta <=90 degree is detecting but theta>90 is not.

My question is how I can map it on mmrotate? Is it possible to add a function to the dataloader which can subtract 180 from the theta?
Need guidance on this.
Thanks
