If you use NE-CAT beamlines for your research work, you are required to acknowledge NE-CAT in your publications.

“This work is based upon research conducted at the Northeastern Collaborative Access Team beamlines, which are funded by the National Institute of General Medical Sciences from the National Institutes of Health (P30 GM124165). The Eiger 16M detector on 24-ID-E is funded by a NIH-ORIP HEI grant (S10OD021527). This research used resources of the Advanced Photon Sourcebeamtime awards (DOI: <add beam time award DOI hyperlinks>) from the Advanced Photon Source, a U.S. Department of Energy (DOE) Office of Science User Facility operated for the DOE Office of Science by Argonne National Laboratory under Contract No. DE-AC02-06CH11357.”

Diffraction images are available on high performance, fast storage for download and processing via RAPD for one week after data collection.  Afterwards, diffraction images are available for download 6 months on spinning disk before movement to long term storage.  Our long term storage is currently tape.  Retrieval of data from long term storage is not guaranteed.  Staff will make our best effort to restore data from tape when requested but this may take days to weeks, depending on the availability of staff.  All RAPD processed results are no longer available as the server at https://rapd.nec.aps.anl.gov/ has been decommissioned.  All RAPD2 processed results are available at https://rapd2.nec.aps.anl.gov/.  All physical processed data files are available for two years from the date of data collection.

Users own the data they collect at NE-CAT and are responsible for sharing it and for its long-term storage, under the data management and sharing policies that apply to their own funding. NE-CAT keeps a copy of raw data on tape on a best-effort basis; it is not an archive of record.

RAPDv2 provides an updated beam center which is written into the header of the image file. On the commandline, type ‘more ‘ to view the header and look for x_beam and y_beam.  The numbers are in pixels.

NE-CAT provides access to HKL2000 for all local users at the beamline. If you need the def.site files for HKL 2000 for processing at your home institution, please download the appropriate beamline here.  If they do not work, double check your beam center. RAPDv2 provides an updated beam center which is written into the header of the image file. If you encounter further trouble, please contact your support person to see if they can help you in this matter.

All data sets processed by RAPDv2 come with an XDS.INP file with a corrected beam center in the tar.bz2 archive.  Generic XDS.INP files are available for download for all NE-CAT beamlines and detectors for processing at your home institution. These files change rapidly, so if they do not work, please contact your support person to see if they can help you in this matter.

Once you are done with data collection, don’t forget to fill out the APS End of Experiment Form (EEF).  Staff will also put out your dewar for return shipping, using the provided return shipping label on Monday through Thursday.
