convergence error_mICA(masked Independent Component Analysis)
Dear mICA developers,

I am using mICA to run group ICA within the cerebellum of 2 year old children. My data is already pre-processed for motion correction and coregistered onto a 2 year old UNC template. I have a cerebellar mask in 4mm space to match my preprocessed func data (4mm Vox size). While running mICA I get the following error: 

Step no. 489 change : -inf
Step no. 490 change : -inf
Step no. 491 change : -inf
Step no. 492 change : -inf
Step no. 493 change : -inf
Step no. 494 change : -inf
Step no. 495 change : -inf
Step no. 496 change : -inf
Step no. 497 change : -inf
Step no. 498 change : -inf
Step no. 499 change : -inf

No convergence -- giving up

It would be great if someone can help me troubleshoot this error.
Thank you for your prompt response.
