2.1.4 QTLdb

As for GLMdb the QTL database consists in as many plain text files as the number of mapping experiments described in the experiment table. Each file must respect the same naming convention as for GLMdb, i.e the stem name of the file must be the name of the corresponding mapping experiment as defined in the map field of the experiment table. Thus if a QTL detection result has been reported for the mapping experiment `exp1' we will have a file exp1.txt. Each file of QTLdb are organized as follows:

     
     group  qtl  position qtl.ci.lod.decrease  qtl.ci.from  qtl.ci.to  qtl.rsquare qtl.trait.name
     1  QTL1  208  1  182  236  0.044  days_to_pollen_shed
     1  QTL2  152  1  128  174  0.045  silking_date
     2  QTL3  74   1  58   88   0.051  silking_date
     2  QTL4  126  1  110  140  0.048  days_to_pollen_shed
     3  QTL6  36   1  18   46   0.093  leaf_number
     8  QTL5  76   1  60   92   0.21   leaf_number
