Hi

I know these messages sound vague, but I can't find more hint to it.

I had ran through gen_be stage 0, stage1 and stage2a with no error messages. However when run stage2, I get 0 eigenvalue and NaN cumulative variance as shown.

-------------------------------------------------------------------------------------------------------

[3] Calculate eigenvectors, eigenvalues and inverse for psi/psi covariance

Mode Eigenvalue Cumulative Variance e(k,k)

1 0.0000E+00 NaN 0.0000E+00

2 0.0000E+00 NaN 0.0000E+00

---------------------------------------------------------------------------------------------------------

No clue at all where went wrong.

gen_be_stage2_nl.nl looks like this :

===================================

&gen_be_stage2_nl

start_date = '2003061700',

end_date = '2003062300',

interval = 24,

ne = 1,

testing_eofs = .true. /

=====================================
