Question concerning tree branch scale and/or lack of branches

[g12342jn]

Hello,

I noticed that with some input files the tree branches are very short or appear to have none, for example (MAFFT+VeryFastTree(17.9k samples):

This also occurs with other external files that I have tried.

Would you be able to let me know why this behavior occurs and how it could be remedied?

Thanks,
Greg

Hi there,
Thanks for the interest.

Definitely it would probably be good to add a tree branch scale. I thought I had an issue for this but not sure where it is

You can also change the "Tree width" in the settings dialog, and this will make the tree draw wider (the vertical divider can be dragged to hide unused portions, so you can make it very wide to enhance certain areas)

Other settings that could help include turning off node bubbles, and making the height very small to see the larger structure of the tree

Hope that helps!

Hello,

Thank you for the information. Turning off the node bubbles and increasing the tree width did have the desired effect, but I did notice that this decreased the scroll performance.

I am in the process of looking through a list of MSA viewers to import into a project and am exploring the usability of this one. I want to see how easily scaling the tree branches would be, and so I have looked through some of the code and found it would be in the TreeBlock component. Do you have any insight on how this might best be implemented?

Thanks Again!

interesting...always interested in increasing performance. there might end up being a need to implement using webgl or something like this to really get good performance.

i was considering adding a scaling bar that would be outside of the treeblock component, probably a new component that would appear above the tree, that you could click and drag to change the scaling
