1. This project (Feng_2009) included 8 F2 intercross Ð 129xA/J, 129xDBA/2, AKRxNZW, BTBRxSWR, C3HxKK, FVBxRIII, PLxCBA and SJLxRIII. Their map were updated to Build37 Cox genetic map and the new files were saved in 8 separated folders (from ÒFeng_2009aÓ to ÒFeng_2009hÓ). These files are ready to be read into Rqtl; 

2. Generated a description file of the project, it includes the general information, definitions of phenotypes, description of genotypes and information of missing markers for both crosses;

3. For folder "Feng_2009a", it has the description and B37 cross file (.csv) of "129xA" F2 intercross;

4. For the genotypes of "129xA" cross: (cM=centiMorgan, bp=basepair)
(1) The authors used SNP markers for this project. All the markers have been converted into standard SNP marker (start with "rs") in B37 data file;

(2) B37 data file had the complete Cox map (cM) and B37 bp positions for all 91 markers; 

(3) There was no X chromosome in this cross


5. For the phenotypes of "129xA" cross:
(1) it only included 336 male mice in total;

(2) Could not find the definition of phenotype "MAP" from paper, it was highlighted with blue color;


6. Except the "csv" file mentioned above, save the description file, original data files, data files with B37 map and data process record together as a big excel file ("Data_Description_129xAJ_Feng2009.xlsx"). (first curating work finished on 5/17/2010, update the description and readme file on 11/9/2010)


7.Information updated on 10/18/2011: 
(1) Change the name of the map (from "Shifman" to "Cox" map) in readme file, add a map reference in description file; 

(2) Quality control plots (genetic map, missing genotypes plot, map comparision plot and whole genome RF plot) performed and no issues found. All quality control plots were saved in ÒQCReport_Feng2009a.pdfÓ.
