Problem aligning ggtree circular tree labels to right angles

Question

[blur]

Hi,

I have made a very nice tree using ggtree package. It is circular but with the fan option - ie it has an open angle. The tree has different clades that I've highlighted and I also added a remark using geom_cladelabel. BUT the labels on the cladelabels are not aligned well, and I tried fixing it with the align option to no avail

the line is:

geom_cladelabel(node=10, label="clade1", color="black", offset =2.6 , fontsoze=1.3)

I tried adding align:

geom_cladelabel(node=10, label="clade1", color="black", offset =2.6 , fontsoze=1.3, align=  T)

Can anyone help? I have 10 labels to adjust and I can't seem to get how...

Thanks
