...ral angles of a folding molecule (attached.
Upon running the 1st iteration of the training function "gtm_trn" I get the following error that I cannot interpret.
Any help and/or suggestion is welcome:
> trnResult = gtm_trn(T, FI, W, lambda, 1, b, 2,quiet = TRUE, minSing = 1.)
Error in gtmGlobalR %*% T :
requires numeric/complex matrix/vector arguments
In addition: Warning messages:
1: In chol.default(A, pivot = TRUE) : matrix not positive definite
2: In gtm_trn(T, FI, W, lambda, 1, b, 2, quiet = TRUE, minSing = 1) :
Using 7 out of 395 eigenvalues
Thank you in advance,
