 ## default YES -- when fstats are scaled to "match" fst in least squares sense 
+*** strongly advuse to specify allsnp: and inbreed: in the paramter file.

+If inbreed: NO the base population (first in poplistname) MUST be a true diploid.   
+inbreed: NO when there are pseudo-diploid populations is dubious but may be necessary, 
+ especially if there is a population with a single sample.  In this case some f2 statistics 
+ can't be evaluated and are set in the output to have huge variance (100).  This means 
+ that in qpGraph some tail edges are set 0 -- really are undertermined.
