Abstract: 
Public datasets are collections of information which are thought to be accessed and (re-)used by everyone. This concept strictly drives all the steps of research routine: from the very initial stages (e.g.: planning the acquisitions) to the final publishing procedures (e.g.: semantic of the data, arrangement of the data). 
Here there will be described the most relevant problems emerging when dealing with data management and basic preprocessing of a multimodal dataset which is going to be published as an open repository. The main focus will be on eye - movements data from a combined Eye - Tracker / FMRI acquisition while participants underwent an ongoing audiovisual stimulus.
The relevant messages would be that 1. There is an entire body of work and really relevant efforts in promoting open access data repositories, but "after - download" phase still needs a bit of fine - tuning; 2. Eye - movements data from ongoing audiovisual stimuli contain interesting information, no matter what is the "level" of deepening; 3. Eye movements data could be related with FMRI ones in several ways: either considering them as something related to noise / artifacts / sensorial information or considering them a source of behavioral information capable of driving both single participant and group level data analysis of higher brain processes.
