1. Update the map of data set with Build37 Cox genetic map (B37) and save the new file as "Wittenburg2002_SWRxAKR_BC_B37_Data.csv". This file is ready to be read into Rqtl; 2. Generate a description file of the project, it includes the general information, definitions of the phenotypes, description of the genotypes and information of the missing markers; 3. For the genotypes of this cross: (cM=centimorgan, bp=basepair) (1) Change the symbol of AKR allele from "1" to "A", heterozygous allele from "0" to "H", missing genotypes from "=" (original data) to "-" (standard format in data sets of QTL archive) and save the changes in B37 data file; (2) Marker "D7Mit362" and "D17Mit10" miss bp positions in both Cox map and MGI. Primer sequences found in MGI, and their locations identified using primer-BLAST in NCBI followed by UCSC In-Silico PCR (this type of markers is highlighted with lime color in description file); (3) Marker "D10Mit75" and "D14Mit166" miss bp positions in both Cox map and MGI. Primer sequences found in MGI, but their locations don't match the result from primer-BLAST, or not target template was found in NCBI primer-BLAST. We could not identify the B37 bp position of this marker currently (this type of markers is highlighted with rose color in description file); (4) The bp position of marker "DXMit19" is missing in both Cox map and MGI. No primer sequences are available for them from MGI. We could not identify the B37 bp positions for this marker currently (this type of markers is highlighted with pale blue color in description file); (5) Three markers are unmapped in Cox genetic map. Their bp positions assigned based on MGI, then convert them into cM through Map Converter tool (this type of markers is highlighted with light yellow color in description file and please see description file for details); (6) Potential genotype errors have been detected by Rqtl program after data input -- 313 male heterozygote genotypes are found on the X chromosome in this reciprocal backcross; 4. For the phenotypes of the cross: (1) The definition of trait "Score2" and "newpathway" are not found in paper (they are highlighted in blue color); (2) The unit information of trait "gallstone_vol" is not found in paper (it is highlighted in blue color); (3) Change the symbol of female mouse in "sex" trait from "F" to "0", male mouse from "M" to "1", save the changes in B37 data file; 5. Except the "csv" file mentioned above, I also saved the description file, original data, data with B37 map, data process and list of missing markers together as a big excel file ("Data_Description_SWRxAKR_BC_Wittenburg2002.xlsx") (1st curating work is finished in 2009, files are updated on 3/2/2011). 6. Information were updated on 5/30/2012: Change the name of the map (from "Shifman" to "Cox" map) in description and readme file, add a map reference in description file.
