=item altparsnpce

  measure alt/par evidence of EVg groups (pubid main/alt "loci")
  a. from mult aligns of cds (using muscle -in evgroupNNNN.cds -out evgroupNNNN.msa )
     .. pairwise align diffs (snp-dif), stats show var(snp) is useful alt/par evd,
     .. combined w/ "spred" of snp-dif, ie snp found over span of align, not just one/two spots
        alts can differ at two ends, identical over main middle, or other like pattern w/ large identical span
        "good" pars have snp single nucl dif scattered over span

  b. from distance tree of mult aligns, (using muscle -in evgroupNNNN.msa -maketree -out evgroupNNNN.tre )
     given MIN_ALT_IDENT (or max distance) cutoff, common branches in tree separate paralogs, w/ alts in each apcut-branch
     Picking cut point for alt/par distance is problem as alts and pars exist in same idenity range (100..90)
     
  Added dna-copynum evidence from gnodes genexcopy (nparalog) aids choice of cut points for a,b.
  Each measure is not reliable for all gene alt/par groups; Combining three measures carefully can improve this

  trial notes in altparsnpce_eqgenetry1a.txt

  .. how to combine evsim (tree common branch cuts) & snp_var ?
   -- require both pass cutoff to call par from alt?
   .. problem w/ tree cutoffs: dist values are *not* pct-ident vals; replace w/ snp Nd/Nc?

 ** Cmpare ref-diff from adupfilt4d/ phiid4d_evsim w/ refdif of altparsnpce4e 
   n=111 in adupfilt4d/at18tair_mrna_phiid4d_evsim_refdiff.list, how many Altbad,Parbad not in altparsnpce4e.refdif?
   .. does altparsnpce4e add useful snpdist filter to phiid4d_evsim?
   .. can evsim global ident + snpdist spread call alt/par w/o dna dupx evidence? No, not reliably;

 >> mix of all 3 dupx evd (dna-tcopy,cds-global-ident,cds-snpvar) sources *might* work out, if properly balanced
     a. evgroup dna-tcopy : 1 (likely join) vs 2+ (likely split)
         .. not all dna-copy seqs in evgroup, and/or evgroup can contain distant parlogs missing dna-xcopy
     b. evgroup global ident (aln-tree-dist) : >99.0(likely join), 99-90 (other evd), <90 (must split)
         .. alts and pars share range in global align idents 90..99+ (including 100% ident)
     c. evgroup snp-vardist (altparsnp..) : <10 (likely join), 10-25 (other evd), >25 (likely split)
	 .. snp-var metric can distinguish alts from pars, but not always reliable
