Hello all,

I am having problems to parameterization using SPHARM-MAT. The problem persists with any data I choose, so I assume is some problem due to my lack of experience using the program. This is the command messages I get when running the exact same experiment than the one contained in the SPHARM-MAT documentation pdf, section 3.2.1., page 20.

Any feedback on the matter will be really appreciated!~
Thanks in advance,
