Hi Berk, Ok, thanks for the info! This will help us to better decide the format for the next project(s).
>> We are currently working on a new set of readers and writers that will support distributed data much better and that will be much more flexible to address various needs. >> It will take us a few more months to get there however. Sounds promising!
