Data retrieval: Formats - ACD
Previous  Next

This section generates a properly formatted and ready-to-use file that you can use as an input file for the ACD (Association Cluster Detector) software*.

1. Enter a Description to identify the process in the top box.

2. Select the field that will be used to segregate cases from controls and which value is associated with either of them.

3. You can choose Batch Mode:

This is a fundamental time-saving feature. Selecting one of the fields in the Samples or SNP table, SNPator will run this process as many times as different values are in that fields, using each time only those samples or SNPs that have each of the values. For instance, if you have defined your samples in the "sex" field as "M" or "W", selecting "sex" as the attribute of the Sample batch mode will result in having two runs of the ACD format retrieval, taking separately men and women.

If you select at the same time sample and SNP batch fields, you are going to obtain as many runs of the process as all possible combinations of the values of samples and SNPs in the fields you selected.

4. The resulting ACD input file is sent to the User Results section. It will be a *.zip file containing several files:

- AcdReport.txt
This is the ACD input file.

- information.txt
SNPator information to identify the job: date, time, user, study and filter.
