Most probably yes. I'm getting this message in the HDF5 stack error: #014: H5Oalloc.c line 1135 in H5O_alloc(): object header message is too large So, yeah, it seems that the HDF5 have not fixed that yet. Until they address it, could multidimensional columns be a solution for you? -- Francesc Alted ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Pytables-users mailing list Pytables-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pytables-users
