Add support for array of arrays?

[maharjun]

The array of array data format is a very commonly used format especially in the context of spiking neural networks (for example while storing spike data). HDF5 (or at-least h5py) seems to have a procedure for storing data of this type. See here.

Note that I'm specifically referring to arrays of arrays containing a single data type. (That single data type may itself be an array thereby allowing recursive array-of-array data).

However, the last I checked, there was no support in Pypet to store data of this format, which is rather unfortunate as now the only option is to pickle the object thereby making it impossible to read in a HDF5 viewer.

In short It would be simply awesome if this data-type was supported.

Hey maharjun, thanks for your remark. Do you have any idea if the arrays of arrays are supported by PyTables?

[maharjun]

The last I checked there was support for it in the form of VLArrays. See below for the link to the documentation.

Thanks, this could work. Unfortunately, I am quite busy until mid of May, but then I'll take a look at it :-)

no support for vlarray yet
