Ne. Xus : data storage format for images, intensities and contextual data Detected :

Ne. Xus : data storage format for images, intensities and contextual data Detected : I(Q) Ii, l Incoming intensity IT Transmitted intensity • Several images are collected for each given sample • Monitoring intensities are also collected for each image • A single Ne. Xus file is generated for the whole sequence J. Pérez, Synchrotron SOLEIL HDF 5 workshop @ ESRF, Grenoble, 2010 Jan 11 -13

Am I happy ? Not completely • I also want to use Foxtrot with data coming from other facilities • But : I don’t want to change Foxtrot code for each new different format • I also want to use other applications (e. g. fit 2 D) on my own data • But : I don’t want to change my data format for each new interesting application A possible solution : Common data format • Long process : Convince each facility to change its own data format ! • Limited to future : You cannot access old data which don’t have the common format Meanwhile, alternative solution : Explain your own present data format • Each facility should provide a plug-in that describes its own data format • Each plug-in would define common simple functions (e. g. Getdata( « type. Of. Data » )) • Each application would have to implement these simple functions ONLY ONCE Light and progressive solution J.
