Ok thanks.
I added in the tool "IDs to check in pedigree:", basically we can use this to build the new groups. You enter here the IDs you want to check in the dog pedigree, for exemple if you want the CZ breeding groups you enter 891,938,929,922,930,876,886,885,796,746,744,914,84 6,924,912 (891=ID of Gar z RosÃkova CS etc... IDs should be separated by comma ,). So now what we need for the new breeding groups is only the right set of IDs.
If you check "sorted", dogs are sorted by weight in the dog pedigree.
Just to see as exemple if we start from
1987 file, to see the 50 first dogs (born after
1987) the most seen in CSV pedigree, use: 622, 940, 796, 928, 938, 852, 765, 948, 937, 945, 935, 1044, 1095, 939, 929, 947, 787, 772, 3584, 1307, 781, 1184, 769, 788, 239, 166, 766, 957, 839, 577, 408, 81, 770, 5431, 1041, 745, 1037, 768, 966, 727, 744, 954, 747, 950, 646, 254, 953, 3551, 164, 746 (just copy/paste in "IDs to check in pedigree:"). Rework this list according to relatives, add/remove/gather, should be a good start. Up to the expert now
