# Results format in colocalization before DF13
**The colocalization data contains data that was acquired by running a colocalization analysis between FinnGen data and other datasets.**
The colocalization results are tab-separated files. The results contain one source1-phenotype1-locus1 source2-phenotype2-locus2-pair per line. More information about data sources, phenotypes and loci can be found in the [Colocalization in FinnGen](https://docs.finngen.fi/finngen-data-specifics/green-library-data-aggregate-data/other-analyses-available/colocalizations) page.
The results contains the following columns:
| Column name | Column description |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| source1 | Data source 1, always FinnGen |
| source2 | Data source 2 |
| pheno1 | Phenotype 1 |
| pheno2 | Phenotype 2 |
| pheno1\_description | Description of phenotype 1 |
| pheno2\_description | Description of phenotype 2 |
| quant1 | Data quantification for phenotype 1. For eQTL Catalog data, this can be exon counts, gene counts, transcript usage, txrevise event usage. For other sources blank. |
| quant2 | Data quantification for phenotype 1. For eQTL Catalog data, this can be exon counts, gene counts, transcript usage, txrevise event usage. For other sources blank. |
| tissue1 | Tissue for phenotype 1 if applicable |
| tissue2 | Tissue for phenotype 1 if applicable |
| locus\_id1 | Locus identifier of credible set of pheno1, locus\_id = top SNP (max PIP). Formatted as CHROM\_POS\_REF\_ALT |
| locus\_id2 | Locus identifier of credible set of pheno2, locus\_id = top SNP (max PIP). Formatted as CHROM\_POS\_REF\_ALT |
| chrom | Chromosome where the loci are |
| start | Start position of intersecting credible sets (in bp, on build hg38) |
| stop | End position of intersecting credible sets (in bp, on build hg38) |
| clpp | Colocalization posterior probability: sum\_i(PIP1\_i\*PIP2\_i). See [Colocalization in FinnGen](/finngen-data-specifics/green-library-data-aggregate-data/other-analyses-available/colocalizations.md) for more information |
| clpa | Colocalization posterior agreement: sum\_i(min(PIP1\_i,PIP2\_i)). See [Colocalization in FinnGen](/finngen-data-specifics/green-library-data-aggregate-data/other-analyses-available/colocalizations.md) for more information |
| vars | Intersecting variants |
| len\_cs1 | Amount of variants in pheno1 credible set |
| len\_cs2 | Amount of variants in pheno2 credible set |
| len\_inter | Amount of variants shared between credible set 1 and credible set 2 |
| vars1\_info | Information about variants in the credible set of phenotype 1. Each variant has its variant identifier, PIP, beta, and p-value. Variant fields are separated by comma, and variants are separated by semicolon. |
| vars2\_info | Information about variants in the credible set of phenotype 2. Each variant has its variant identifier, PIP, beta, and p-value. Variant fields are separated by comma, and variants are separated by semicolon. |
| beta1 | effect size of lead SNP in locus 1 |
| beta2 | effect size of lead SNP in locus 2 |
| pval1 | p-value of lead SNP in locus 1 |
| pval2 | p-value of lead SNP in locus 2 |

# 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/finngen-data-specifics/green-library-data-aggregate-data/core-analysis-results-files/colocalization-results-format/results-format-in-colocalization-before-df13.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.
