Dear all,
I just started using DCM (for cross spectral density) and stumbeled over two error messages the first (related to first screenshot "two_conditions")was:Undefined function or variable 'A'. Here I specified between trial effects and therefore had two conditions.
...
evaluating condition 2 (trial 106)
evaluating condition 2 (trial 107)Undefined function or variable 'A'.

I tried to make it more easier and only used one condition. Here the evaluation worked, but after convergence the error below came up (related to screenshot "one_condition"):
...
EM:(-): 15     F: 8.434e+04 dF predicted: 9.911e-03  actual: -2.534e+04 (2095.69 sec)
EM:(-): 16     F: 8.434e+04 dF predicted: 1.341e-03  actual: -2.534e+04 (2066.97 sec)
EM:(-): 17     F: 8.434e+04 dF predicted: 1.815e-04  actual: -2.534e+04 (2081.01 sec)
EM:(-): 18     F: 8.434e+04 dF predicted: 2.457e-05  convergence
Index exceeds matrix dimensions.


Did anyone encounter the same errors and has a solution? Any clues why those errors appear are appreciated!

Thanks a lot!
Johannes
