What Fluxus essentially does is represent, in a visual manner, the relative relatedness of the haplotypes you input. It's based on the mutations/differences between the haplotypes but how it actually does it, I couldn't begin to tell you. I have seen some links on their website to what I expect are academic papers explaining some of the workings/ideas behind the software. I've not taken the time to really delve into it. Sort of like I know basically what a TV does but I really have no idea how to build/fix one. What I see coming out of the Fluxus software corresponds very closely [I'd say exactly really] to what I've done using the calculations of TMRCA's and genetic distance when grouping the results for Clan MacMillan. I like the fact that my initial grouping are being validated by a second method. For question 'a' above: I maintain the Clan MacMillan results in a spreadsheet. Initially, I was converting the Excel file to a comma delimited file, doing some other clean up, adding required headers etc. and then saving the results as a *.ych file. That is an error prone way but I managed by being careful and the fact I deal with file manipulation in my job, daily. A much easier way, is by using Dean McGee's Y-DNA Comparison Utility... http://www.mymcgee.com/tools/yutility.html . You'll still need to have your haplotype data in a spreadsheet format in order to load it into the utility but it does the conversion to the *.ych format for you. For question 'b' above: all data is coming from my input. David M

Many thanks, David. Now I've got a much clearer understanding of the process. -Bill ----- Original Message ----- From: "David" <dmcduke@comcast.net> To: <SCOT-DNA-L@rootsweb.com> Sent: Sunday, March 26, 2006 2:00 PM Subject: Re: [SCOT-DNA] cladogram > >I don't understand how Fluxus works, and can't find anything on their > > website that explains it. > > > > a.
