Does anyone know how to export lta files's animation

I wanna convert the crossfire models to cs:go models,but I don't know how to export the animation in the modedit,does anyone know? Sorry For My Bad English..

The file contains the bones, the bones matrix, the bones weights, the animations key-frames... what else do you need? just open the file as a text file and check it yourself.

thanks reply，but I thy to find the relationship between the lta file and cs:go smd file animation code,I failed ...
