Dear FreeSurfers,
On my maiden voyage with selxavg3, I've encoutered an error and could use some help. After processing several subjects successfully, selxavg3 quit unexpectedly. Here is the exact message: Warning: matrix is singular to working precision > In fast_selxavg3 at 208 ntptot = 666, nX = 31, DOF = 635 ??? Error using ==> svd Input to SVD must not contain NaN or Inf. Error in ==> cond at 40 s = svd(A); Error in ==> fast_selxavg3 at 235 XCond = cond(XtX); Can anyone help me track down the source of this error and/or suggest a fix? Also, in the course of reviewing the error I saw the following notice: INFO: Key -timeoffset unrecognized, line 7, skipping I have the "timeoffset" argument set to half a TR in my mkanalysis step because I included slicetime correction during preprocessing. Does selxavg3 not recognize this option? Thanks in advance for any help you can provide.
