XDSCC12 is a program for generating delta-CC<sub>1/2</sub> values. It implements the method described in Greta Assmann, Wolfgang Brehm and Kay Diederichs (2016) Identification of rogue datasets in serial crystallography. J. Appl. Cryst. 49, 1021 [http://journals.iucr.org/j/issues/2016/03/00/zw5005/zw5005.pdf], but instead of for individual datasets, it does it for individual frames, or groups of frames, from a single dataset collected with the rotation method and processed by [[XDS]].
XDSCC12 is a program for generating delta-CC<sub>1/2</sub> values for XDS_ASCII.HKL, or for XSCALE.HKL containing several files of type XDS_ASCII.HKL after scaling in XSCALE (with MERGE=FALSE).  


The program can be downloaded for Linux 64bit[ftp://turn5.biologie.uni-konstanz.de/pub/xdscc12.rhel6.64] or Mac[ftp://turn5.biologie.uni-konstanz.de/pub/xdscc12-mac].

Usage (this text can be obtained with xdscc12 -h):
<pre>
usage: deltacc12 -dmin <lowres> -dmax <highres> -nbin <nbin> -mode <1 or 2> -<abcdeftwz> FILE_NAME
dmax (default 999A), dmin (default 1A) and nbin (default 10) have the usual meanings.
mode can be 1 (equal volumes of resolution shells) or 2 (increasing volumes; default).
  -t: total oscillation (degree) to batch fine-sliced frames into
other options can be combined (e.g. -def), and switch the following off:
  -a: individual isomorphous summary values
  -b: individual (Fisher-transformed) delta-CC1/2 values
  -c: individual delta-CC1/2 reflection numbers
  -d: individual anomalous summary values
  -e: individual (Fisher-transformed) delta-CC1/2ano values
  -f: individual delta-CC1/2ano reflection numbers
  -w: weighting of intensities with their sigmas
  -z: Fisher transformation of delta-CC1/2 values
</pre>
 
The program output is terse but supposed to be self-explanatory. Part of it is most easily visualized via XDSGUI, however, that currently deals with the isomorphous signal of a batch of frames (width chosen with the -t option) relative to all data.
 
For multiple datasets, the output lines show the contribution of each dataset toward the total CC<sub>1/2</sub>. Negative numbers indicate a worsening of the overall signal.
 
All statistics are given for the isomorphous and the anomalous signal.
