# When moving from BCOR to .txt files, what does the column called "correlation" mean? The "correlation" column is the same as R^2. Idstore (which generates the result) does not return which alleles are linked so you cannot determine that from the output in the file. The value reported is in-sample (i.e. using the cases and controls that were used in the association analysis). The value in Idstore is actually just pure correlation, hence negative values will appear. The imputed data we provided as VCFs is phased, so you could extract the variant of interest carriers and those 5 variants to see what the haplotypes are. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.finngen.fi/faq/about-finngen-data/untitled-1.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
