cai-1 cell ROI masks

Dear all,

The cai-1 dataset, and then the GCaMP6s and GCaMP6f datasets within that, contain two sets of data:
1. the raw imaging in the form of tiff files

2. the extracted fluorescence traces from the raw imaging files, + electrophys

My question is: are the region of interests masks which were used in extracting the fluorescence from the raw imaging also available? The data-format pdf (http://crcns.org/files/data/alm-1/Svoboda_lab_data_format_general.pdf) mentions a roiMap struct, but this does not seem to be included with the dataset.

Apologies if I've just missed them.

Thanks!
