Print Z1 Photos in Tif or Raw . . .What App?

I am new to 360 but not raw. I (begrudgingly) downloaded LRC so that I can edit and stitch my Z1 files. But if I output a TIF file, neither Theta nor Insta360 Studio will allow me to manipulate the image. My objective is to create a workflow and keep the most detail possible for print (not the internet). Anyone have a solution?
