1. Update the map of data set with Build37 Cox genetic map and save the new file as "Kiernan2007_B6xC3H_B37_Data.csv". The file is ready to be input into Rqtl; 2. Generate a description file of the project, it includes the general information, definitions of phenotypes, description of genotypes and information of missing markers; 3. For the genotypes of the cross: (cM=centimorgan, bp=basepair) (1) The data set of this cross only has 19 autosomes; (2) The direction of the cross is (B6xC3H) F1 x C3H backcross. It should only have allele "C" and "H" inside. But Rqtl program dectects 3 "B6" alleles and two empty cells in original data file after data input. I change them as missing values and save the changes only in map updating file "Kiernan2007_B6xC3H_B37_Data.csv". It is ready to be input Rqtl; (3) The bp positions of marker "D2MIT17" and "D3MIT19" are missing in both Cox map and MGI. Primer sequences found in MGI, but their locations don't match the result from primer-BLAST in NCBI. We could not identify the B37 bp position of this marker currently (the letters are highlighted with pink color in description file); (4) Marker "D14MIT75" misses bp position in both Cox map and MGI database. No primer sequences are available from MGI. We could not identify the B37 bp position for this marker currently (its fonts are highlighted with blue color in description file); (5) Marker "D4MIT26" misses bp position in both Cox map and MGI database. Primer sequences found in MGI, and their locations identified using primer-BLAST in NCBI followed by UCSC In-Silico PCR (it is highlighted with green color in description file); (6) Seven markers miss their bp positions in Cox genetic map, assign the position from current MGI database. This type of markers are highlighted with orange color and please see description file for details; 4. For the phenotypes of the cross: (1) The information of mouse sex, diet and aging at test are not in the paper. Mark them with text "not in paper" in description file; (2) Do not find any phenotypes named as "lineage" which mentioned in Renhua's README file, it may be removed by author during data analysis; 5. Except the "csv" file mentioned above, save the description file, original data, data with B37 map, data processing record and missing marker list together as a big excel file ("Data_Description_B6xC3H_Kiernan2007.xlsx"). (first curating work finished at 5/28/2009, files updated at 7/2/2009, 12/1/2010). 6. Information updated on 10/27/2011: (1) Changed the name of the map (from "Shifman" to "Cox" map) in description and readme file, add a map reference in description file; (3) Generate genetic map plot, missing genotypes plot, map comparison plot, whole genome RF plot and problematic chromosome RF plots for B37 data. Problematic markers were found on chr 2, 8, 9, 10, 18 and 19. All quality control plots were saved in "QCReport_Kiernan2007.pdf".
