RE: Signifcant but have "+0" change

[Malabady]

Hello:

A number of the gene families are significant (Base, p=0.004), but the number of gene change is "+0" in the base change file. Is this normal? if yes, what does it mean?
Here is an example:
from Base_family_results.txt:

OG0000096 0.004 y

From Base_change.tab:

FamilyID	My Species	Species A	Species B	Species C	Species D	<5>	Species E	<7>	<8>	<9>	Species F	<11>	Speices G	<13>	Species H	<15>	Species I	<17>
OG0000096	0	4	-6	-3	1	1	5	-2	0	0	2	1	-2	1	8	0	-5	0

Thank you for the help,

I think the p-value you have asked for is for the whole tree, not branch-by-branch. So CAFE is telling you this family is significant, but not on any particular branch.
