[Nexus] Writing and reading Nexus files in Matlab

[freddie.akeroyd at stfc.ac.uk]

If the NeXus files are in hdf5 format then reading is relatively easy -
matlab provides commands to load the data directly into a matlab array.
For more details see  

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/hdf5read.html

with regard to writing, nexus adds additional attributes to an HDF5 file
to indicate the "nexus class" of an item. It would be possible to create
a NeXus file using the matlab hdf5write command, but you would need to
add these additional attributes by hand to make it readable by other
nexus utilities. These problems would be solved by a native matlab API
for NeXus - it is on the todo list, but we haven't quite got round to it
yet. What sort of timescale were you looking at to start using NeXus
files?

Regards,

Freddie

Dear all,

I would like to store my datafiles of upcoming 1D and 2D synchrotron
SAXS experiments in the NeXus format for archival purposes. I am only
familiar with Matlab, however I have not seen any API for Matlab NeXus
writes. Can someone please indicate how I can go about this?

Yours sincerely,


Brian R. Pauw.
