Dear eeglab,

Recently Im facing a problem when running multiple AMICAs in a super-computer at once, where I get the following error:


 iter   258 lrate =  1.0000000000 LL =  -0.0238247322 nd =  0.0001777274, D =   0.89129E-01  0.89129E-01  ( 33.34 s, 182.8 h)
 iter   259 lrate =  1.0000000000 LL =  -0.0238213053 nd =  0.0001768634, D =   0.89103E-01  0.89103E-01  ( 34.18 s, 187.4 h)
 iter   260 lrate =  1.0000000000 LL =  -0.0238178712 nd =  0.0001762253, D =   0.89076E-01  0.89076E-01  ( 33.08 s, 181.4 h)

However, this error doesn the error doesnt generate an error in matlab so it tries to proceed forward and uses the ICA weights from the most recent iteration. Obviously this isnt ideal, as AMICA requires a lot of iterations to get good ICs.

Does anyone have any idea how to fix this or find a work around? I can confirm that there are no jobs using the same temporary file, temporary output folder, or any of the functions that are run in AMICA. They are all copied to their own folder and run independently. At least thats what I hope is happening.

Im running out of things to try.
