1. This project (Su_2009) included several crosses and we received data sets of 2 crosses -- B6xC3H F2 intercross and NZOxNON backcross. The NZOxNON cross was also used in Maternal environment and genotype interact to establish diabesity in mice Reifsnyder PC, Churchill G, Leiter EH. Genome Res 2000 Oct;10:1568-1578. PMCID: PMC310941. The phenotypes of the backcross has been merged and users can find the data set under "Reifsnyder2000" project folder. The map were updated to Build37 Cox genetic map and the new files were saved as "Su2009_B6xC3H_B37_Data.csv" and "Reifsnyder2000_NZOxNON_B37_Data.csv". These two files are 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) Correct name of maker "D19MI68" to "D19MIT68"; (2) The bp position of marker "D3Mit19" is missed 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 of the marker are highlighted with pink color in description file); (3) 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 (it is highlighted with pale blue color in description file); (4) Six markers miss their bp positions in Cox genetic map, assign the positions from current MGI database. This type of markers are highlighted with orange color and please see description file for details; (5) There was no X chromosome in this cross file; 4. For the phenotypes of the cross: This cross only had 277 female mice in total and no more problems are found in phenotypes; 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_B6xC3H_Su2009.xlsx") (1st curating work is finished on 4/8/2010, files are updated on 4/15/2010, 2/10, 2/16/2011). 6. Information were updated on 5/25/2012: Change the name of the map (from "Shifman" to "Cox" map) in description and readme file, add a map reference in description file.
