### Description

This column shows the ID of the probe in the GNF Atlas 2 that overlaps most with the selected gene. The GNF Atlas 2 is based on two Affymetrix chips: the U133A and a custom-designed GNF1H chip.

### Methods

Target sequences for U133A were downloaded from the Affymetrix Product Support website. Target sequences for GNF1H were obtained from GNF via personal correspondence. The sequences were mapped to the genome using `blat` followed by `pslReps` with the parameters -minCover=0.3 -minAli=0.95 -nearTop=0.005. For each gene, the target with the greatest overlap (on the same strand and excluding introns) was chosen.

### Credits

The data for this column were kindly provided by GNF as part of the GNF Gene Expression Atlas.
