GrASP 0.6 beta
GrASP (Graphical Assessment of Sliding P-values) is a graphical tool to display and assess p-values from sliding window tests. It can present thousands of p-values from the sliding window tests as a simple graphic that uses varying levels of user-specified color to indicate the width of the sliding windows and the varying levels of significance. It therefore allows the user to identify regions/blocks of interest from these sliding windows, based jointly on the absolute p-value of the tests from these windows and the building of haplotypes of significance in the region. GrASP is executed as an Excel macro and is written in Excel’s built-in version of Visual Basic for Applications.
