Color-coded gene trap frequency track for MGI genes, indicating the number of gene trap insertions per gene. Only gene trap insertions that "trap" a gene (i.e., overlap the gene's coordinates in the correct transcriptional orientation) are counted. Color is as follows; Red= Over 1000, Orange= 101 to 1000, Green= 11 to 100,Blue= 2 to 10, Violet= 1, Black=0. This track was generated from the file available on the MGI FTP site at /pub/reports/ALL_CellLine_GeneTrap.rpt
