Incomplete values
Incomplete values (like 18.2, 24.3, 15.1 and such) are not supported in Internet version. Reason is simple: lists (one for every STR marker) does not have incomplete values in their contents, because it could be too heavy burden. Desktop edition of NevGen (not available on internet) does have support for incomplete values in its structures, code and data, and uses them because it does not work with lists for STR values. But, it has them in STR frequency statistics only for three STRs and three haplogroups (.2 for J1 subclades on DYS458, .3 on DYS390 for N1a and .2 on DYS385a for several haplotypes in I2a2-L38). Incomplete values could be great to ease haplogroup determination, but problem with them is that they are not easily recognized in public haplotype data. FTDNA projects does not display them, except in some cases in rows with MAX and MIN values for sections. In most cases that is not enough to establish where they could be found. That is pity, because they could greatly enhance haplogroup prediction.
Advice (especially for haplotypes from J1 haplogroup): when entering haplotypes into NevGen Edit field please remove all uncomplete values. Using them shall lower Fitness scores and probability!
