NOTE: This window essentially accomplishes the functions of the right tab of the Association Test Window, except it is not necessary to simultaneously perform an association test to use this window.

18.10.1 Data Requirements

General marker statistics require a data set containing genotypic data. Optionally, case/control data will be used to subdivide most of these statistics according to “case” and “control”. First import your data into a HelixTree project (See Chapter 4). Once you have the spreadsheet for this data, select the column representing the case/control status as the dependent variable (See Section 6.2) if you wish to subdivide your statistics by “case” and “control”. Then access the General Marker Statistics options dialog by selecting Genetics->Marker Statistics from the spreadsheet menu.

NOTE: If you have case/control data with some missing values, see 18.4.2. You can still (optionally) have your statistics subdivided by “case” and “control”.

18.10.2 Processing

Select your marker statistics options and select the Run button to process. Please see 18.7 for an explanation of the options for this window.

One spreadsheet will be output with the results.

NOTE: The markers that were skipped (because of not being bi-allelic) will be included in this spreadsheet, but the data for those markers will be displayed as missing values.
