a question about Bitstream Header.
Hi,
I have a question about the format of Theora bitstream header.
It seems to me that there are differences between the specification[1]
(version 2004 Oct 1) and its reference implementation in
libtheora 1.0alpha3 released at 2004 Jun 1.
I mean that... please refer to Section 6.2 'Identification Header Decode'
in that specification[1] and the function

...e all the B taxa arise in a true polytomy from A1 and B2 is the
ancestor of C1 which is the ancestor of D1
I have information on all the taxa and can create independent contrasts
for this:
x<-c(B1=47,D1=43,C1=45,B2=50,B3=47,B4=48,A1=48)
y<-c(B1=2.9,D1=5.4,C1=2.8,B2=3.5,B3=3.2,B4=3.5,A1=1.8)
picx<-pic(x,phy=tree)
picy<-pic(y,phy=tree)
Which seems to make sense. However, if I try to use anything more
sophisticated I run into problems:
>dat<-as.data.frame(cbind(x,y))
>model1<-gls(y~x,data=dat, correlation=corBrownian(phy=tree))
Error in corFactor.corStruct(object) : NA/NaN...
