 If you use a file as input list, it is necessary to specify the column number on which to apply the comparison.
 
+Ids in a line will be split by ";", so if you have this kind of input :

+All ID will be considered (i.e. Q06830,P60709,P13646 and P31949 will be split).

+In copy/paste mode, the number of IDs considered in input is limited to 5000.
