Number of Components = TRs - 1 in tedana

When running tedana, I sometimes get a number of components equal to the number of TR’s - 1. Is this an expected behavior of the program?

Hi,

I am also obtaining number TR - 1 components. The results indicate that out of 504 components for task fMRI, only 12 are signal, with an explained variance of ~10%.

Does this sound correct?

Best.

Note for future users: this is a fixed bug from a release of tedana earlier this year. Please update your tedana installation if you have this problem.
