Dear Dr. Alfonso,

Hope you are doing well. I was playing around with the Conn preprocessing modules and have spotted two behaviour which might not be expected:

1. When running the pipeline in parallel on a local machine, if we select skip slice timing correction, the pipeline does not work but throws up the following error (default pipeline):

The pipeline runs fine in parallel if slice timing is specified or when serial processing is selected.


2. When using the indirect normalization pipeline (MNI), the functional files also get normalized to the voxel size of structural images. The GUI prompts to specify the dimensions of structural and functional image for normalization. The default input for structural is 1 while functional is set to 2 (and is grayed out in indirect pipeline). However, the end result is functional files having voxel dimension 1x1x1. They get normalized to 2x2x2 if the structural is set to 2. Possibly somewhere in the batch, the functional voxel size is wrongly specified to match the structural voxel size?


Both the above were tested using Conn 18.a on MATLAB 2016a running on a RedHat machine. Please let me know if you need any more information.



Thanks and Regards
