Is there away to punch in the exact values to rotate a surface along various axes in SUMA?
Do you mean, as you visualize a data set in SUMA and hit the arrow key, how much the brain rotates?
Firstly, you should have a file of SUMA environment variables file called "~/.sumarc’. If you don’t, then type:
$ suma -update_env
to create one of defaults. Then, you can edit the variable ‘SUMA_ArrowRotAngle’, which will likely be at the top of the list (pasted here, with commented description:
// 000-SUMA_ArrowRotAngle: // Incremental arrow rotation angle in degrees // default: SUMA_ArrowRotAngle = 5 SUMA_ArrowRotAngle = 5
Is that what you are looking for?
Thanks Paul, I was mainly interested to know if there is a place where I can enter exact values of rotation along axes instead of hitting keys multiple times to get to the view I like.
If you mean rotate the surface definitions rather than just the view, ideally, it would be done completely within ConvertSurface, but you can do it without too much trouble by rotating a corresponding volume with 3drotate. 3drotate will compute the affine transformation and puts that transformation into the header of the output dataset. Extract that matrix with cat_matvec to use with ConvertSurface -xmat_1D.
