Matrix Format

Genotypes can be downloaded here in a Matrix Format that can be easily imported in most data programs as Excel, Spss, etc.

You can choose whether to put SNPs in rows (getting SNPs x Samples) or in columns (Samples x SNPs).

SNPs will be ordered in alphabetical order unless you select the option "Order SNPs by Chromosome and Position".

A Report file separated by tabs or spaces will be generated depending on the settings of the second option.

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 Matrix Format genotypes 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.
