# Simple XDS_PAR

## **Introduction**

[This job template](https://app.dectris.cloud/sections/library/jobs/templates/public?id=01975702-e4df-7243-9c16-8700b9f70c3b) has been built with the [XDS](https://help.dectris.cloud/en/article/xds) environment and runs `xds_par` on a selected dataset. The user must define a path to an `XDS.INP` file that has been uploaded to either a project or experiment folder.

## **Quick Start**

To run this job, you need to provide two input parameters, which are both path variables: (1) The **path to the dataset** to be analyzed (file not folder), (2) The **path to the pre-generated XDS.INP** file to be used. Both of these parameters are defined using the file browser within the job launcher:

In the above example, an `XDS.INP` file has been uploaded to the work directory of the experiment. The job template ensures that the chosen path gets inserted into the `XDS.INP` file before running `xds_par`. It also ensures that, in case the input data is of hdf5 format, the correct path gets set to the dectris-neggia.so plugin. 

## **Output**

A successfully completed job generates the following output files:

-   At the top level of the output folder, the following plots and files are defined: 
    -   `CC_HALF_vs_Resolution.png`: A plot of CC1/2 as a function of the resolution limit.
    -   `COMPLETENESS_vs_Resolution.png`: A plot of the completeness as a function of the resolution limit.
    -   `I_SIGMA_vs_Resolution.png`: A plot of the Mean I/σ(I) as a function of the resolution limit.
    -   `R-MEAS_vs_Resolution.png`: Redundancy-independent R-factor (%) as a function of the resolution limit.
    -   `correct_summary.txt`: Crystallographic statistics extracted from the CORRECT.LP
    -   `refined_unit_cell.txt`: The refined unit cell
-   Within the subdirectory xds\_output, the typical XDS output files can be found:
    -   ABS.cbf
    -   COLSPOT.LP
    -   CORRECT.LP
    -   DEFPIX.LP
    -   GXPARM.XDS
