Durin
=====
XDS plugin for reading HDF5 files following the NeXuS format or those written by Dectris Eiger detectors.
See:
* https://www.nexusformat.org
* https://www.dectris.com/features/features-eiger-x/hdf5-and-nexus
* https://strucbio.biologie.uni-konstanz.de/xdswiki
## Get Durin
Latest release at https://github.com/DiamondLightSource/durin/releases/tag/2019v1
## Usage
In your XDS.INP add:
```
LIB=[path to durin-plugin.so]
NAME_TEMPLATE_OF_DATA_FRAMES=[data_path]/data_images_??????.h5
```
XDS will instruct the plugin to load `[data_path]/data_images_master.h5` and this must be the
Eiger master file or the NeXus file for the data collection.
It is generally assumed that the files `[data_path]/data_images_data_xxxxxx.h5` contain the actual
datasets and the master file contains HDF5 external links to these, but that is not required, so long as
the master file contains an `NXdata` or `NXdetector` group with either a dataset named `data` or a
series of datasets named `data_000001`, `data_000002`, etc.
## Requirements
* HDF5 Library (https://www.hdfgroup.org/downloads)
## Building
### Building HDF5 library
The HDF5 library used when building durin must have been compiled with specific switches enabled
to allow the durin plugin to be built and used.
Download the HDF5 source code (https://www.hdfgroup.org/downloads/hdf5/source-code) and extract
to any directory (referred to as `/hdf5_dir`), and run the following commands.
```
cd /hdf5_dir
mkdir build
cd build
export CFLAGS=-fPIC
../configure --enable-threadsafe --enable-deprecated-symbols --enable-hl --enable-unsupported
make
make check
make install
```
The hdf5 tools and libraries should now be located in `/hdf5_dir/build/hdf5`
For reference, the plugin requires the thread-safe switch and the optimised chunk read function.
The chunk read function may be defined in the high level library instead of the regular library,
depending on the exact HDF5 version downloaded (hence the --enable-deprecated-symbols _and_ --enable-hl).
The unsupported flag enables building with both threadsafe and high-level enabled.
### Building durin plugin
The plugin makefile will use the "h5cc" compiler wrapper, provided by the HDF5 library, which
must be on your PATH.
Download or clone the plugin source code (https://github.com/DiamondLightSource/durin)
into any directory (referred to as `/durin_dir`) and run the following commands.
```
cd /durin_dir
PATH=/hdf5_dir/build/hdf5/bin:$PATH
make
```
The plugin is located at `/durin_dir/build/durin-plugin.so` and should be added to the
XDS.INP file as `LIB=/durin_dir/build/durin-plugin.so`
## Example XDS.INP
```

N.B. the master file is needed, not the .nxs one which follows the
standard.
