Hi,
I am looking for a way to share some raw k-space data along with our BIDS-formatted fMRI data set. As these raw data probably do not comply with BIDS formatting we thought to maybe include them in a bids ignore file when we upload to openneuro? But then these data are quite large and it feels weird to ignore the largest part of the dataset. 
Also as there seem to be different standards for these kinds of data (like the ISMRM Raw Data Format) it might even be the better option to share that part separately elsewhere and to state that these datasets are connected? What are your thoughts on this? Does anyone know about platforms that host these sorts of raw data?
Thanks a lot for your help!
