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;

3. For folder "Feng_2009e", it has the description and B37 cross file (.csv) of "C3HxKK" F2 intercross;

4. For the genotypes of "C3HxKK" 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) The bp position of marker "rs3709824" is missing in Cox genetic map, assign the position from current MGI database

(3) There was no X chromosome in this cross


5. For the phenotypes of "C3HxKK" cross:
(1) it only included 335 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, data process record and missing marker list together as a big excel file ("Data_Description_C3HxKK_Feng2009.xlsx"). (first curating work finished on 5/17/2010, files have been updated on 11/10/2010).


7. Information updated on 10/20/2011: 
(1) Change the name of the map (from "Shifman" to "Cox" map) in description and readme file, add a map reference in description file; 

(2) Generate genetic map plot, missing genotypes plot, map comparison plot, whole genome RF plot and problematic chromosome RF plots for B37 data. The last marker on chr 6 might have a problem (observed from map comparison plot). All quality control plots were saved in ÒQCReport_Feng2009e.pdfÓ.
