A new flexible integration of NeXus datasets to ANKA by FUSE file system

In the high data rate initiative (HDRI[1]) German accelerator and neutron facilities of the Helmholtz Association agreed to use NeXus[2] as a common data format. The synchrotron radiation source ANKA[3] decided in 2012 to introduce NeXus as common data format for all beam lines. Nevertheless it is a challenging work to integrate a new data format in existing data processing work flows. Scientists rely on existing data evaluation kits which require specific data formats. To solve this obstacle, for linux a file system in userspace (FUSE)[4] was developed, allowing to mount NeXus-Files as a file system. Easy in XML configurable filter rules allow a very flexible view to the data. Tomography data frames can be directly accessed as TIFF[5] files by any standard picture viewer or scan data can be presented as a virtual ASCII[6] file compatible to spec[7].
