When I did this a few years back I read (H5Dread) a value of out a dataset, then watched the output with strace to get the offset. Not pretty, but it worked for what I wanted to do. Quincey said something more hdf5-native would be interesting, pending funding to work on it. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Hdf-forum is for HDF software users discussion.
