It is a bit hard to say... The netCDF support is a bit rudimentary which is probably due to a lack in usage. About a year ago I was playing with DX 4.1.3 and netCDF and found some fundamental problems with memory management that I was able to fix and which have been included in releases later than 4.1.3. At this point I tried to be careful so as not to modify any behaviour in the module, but only fix some fundamental problems that caused it to crash. My impression is that the module was written to accomplish a certain set of tasks (although with an attempt to be fairly general). There are some cases where the code will do things that are maybe not obvious, and maybe even not completely according the documentation in the HTML manual. Certainly there are cases where the documentation is a bit vague and the behaviour of the module may be unexpected for this reason. I am not quite sure what you are trying to achieve. At a first glance I get a bit puzzled about reallocations being (2,ny,nx) and not (ny,nx) or (Time,ny,nx). Maybe there also should be a densityrecv:positions = "reallocations" attribute in your data file and that reallocations should not have a "field" attribute. Maybe if you were to tell in more detail what you want to do and put that together with your net and data files on a web-page or something I would be able to have a better look at it. I am not sure if the DX importer can handle the positions being a time series if that is what you are after. And if it would, I'd be surprised if it can handle that the time series not being the same length for reallocations and densityrecv (2 and 10 respectively). Maybe you could get around this by explicitly only importing one set in each of two separate import modules, using the variable name parameter to the import module? That's my 2c at the moment. Hope they can be of some help. Good luck! /Nils
