@copilot review the current state of the code: I made some changes outside this thread, but I pushed them to this branch. The headline is that things have progressed. Phylotree.js is being loaded correctly and it is attempting to draw a tree. However, the tree that I uploaded is a cladogram: And phylotree.js is seemingly unprepared for this, as per the javascript console: So, what I would propose is the following:
|
- Add isCladogramNewick() function to detect trees without branch lengths - Add convertCladogramToUltrametric() function to add unit branch lengths - Display notice when viewing a cladogram - Hide scale bar and branch length info for cladograms - Enable align-tips for cleaner cladogram visualization - Fix regex to handle scientific notation in branch lengths - Apply changes to both treeViewer.jsp and treeViewerInline.jsp Co-authored-by: rvosa <106490+rvosa@users.noreply.github.com>

@copilot there are still rendering issues. The javascript console shows that there are still I set a breakpoint in phylotree.js line 883, and this is the call stack: Do a thorough analysis of what might be going on here and fix this. |
The previous regex pattern produced orphan colons (`:` without numbers) which caused phylotree.js to compute NaN values for SVG coordinates. Fixed convertCladogramToUltrametric() in both treeViewer.jsp and treeViewerInline.jsp: - Process leaf names first, then internal nodes (closing parens) - Include dots in taxon name pattern for species like B.guascoi - Simplified regex to properly add :1 after all nodes Example: (A,(B,C)); -> (A:1,(B:1,C:1):1):1; Co-authored-by: rvosa <106490+rvosa@users.noreply.github.com>

@copilot Why are you doing regexes on the newick string? That seems like a highly fragile approach. Isn't there an option to parse the newick first with phylotree, and then traverse the topology to add branch lengths? Furthermore, I explicitly asked you to lengthen the terminal branches to make the tree ultrametric and there's no way you'll be able to do that in the way you've been working, with string manipulation. |

@copilot there is something weird going on. Notice this function from phylotree.js: function defBranchLengthAccessor(_node, new_length) {
let _node_data = _node.data;
if (
"attribute" in _node_data &&
_node_data["attribute"] &&
_node_data["attribute"].length
) {
if(new_length > 0) {
_node_data["attribute"] = String(new_length);
}
let bl = parseFloat(_node_data["attribute"]);
if (!isNaN(bl)) {
return Math.max(0, bl);
}
}
// Allow for empty branch length at root
if(_node_data.name == "root") {
return 0;
}
console.warn('Undefined branch length at ' + _node_data.name + '!');
return undefined;
}I think it expects |
phylotree.js defBranchLengthAccessor expects attribute to be a string because it checks attribute.length (which only works for strings, not numbers). Changed assignments from numeric 1 to string "1" and wrapped calculations in String() to ensure compatibility. Co-authored-by: rvosa <106490+rvosa@users.noreply.github.com>

The root node was not getting an attribute set, which caused defBranchLengthAccessor to return undefined (since the empty/missing attribute fails the truthy check). This undefined value propagated through calculations and produced NaN in SVG coordinates.

@gaurav I don't recall us having run into undefined branch length issues when parsing cladogram Newick strings into phylotree. Just wondering whether you have any insights here to share. |

@copilot The render() call from phylotree.js creates an SVG but doesn't appear to append it to the container. The render method returns a renderer object, and you need to either:
Inspect carefully how this is being done in this example: https://phylotree.hyphy.org/# |
The render() method in phylotree.js creates a TreeRender object that builds the SVG internally, but doesn't automatically append it to the container. Following the pattern from the reroot() function in phylotree.js (line 9792), we now: 1. Store the returned renderer object from render() 2. Call renderer.show() to get the SVG element 3.

@copilot While rendering the tree, various elements in the SVG are supposed to be assigned a translate() attribute, but the first argument that is being inserted in the translate is an NaN. We get to that point via the following call stack: What I am also noticing is that the element itself has no width or height attributes. What I am assuming is that the tree object itself is fine (I inspected it and the nodes have height and depth attributes) but that the canvas dimensions are not being set properly and therefore the coordinates of the nodes and branches cannot be calculated. I am asking you, once again, to look very carefully at the deployment example given here: https://phylotree.hyphy.org/# Check if some defaults need to be provided for the element, or something like that. Check if the settings for width and height that are being passed into |

The phylotree.js library already detects cladograms in its constructor
and sets all branch lengths to 1 via setBranchLength((x) => 1). Our
custom makeUltrametric() function was conflicting with this.
Changes:
- Remove checkIfCladogram() and makeUltrametric() functions
- Use simple string check (!newick.includes(':')) for cladogram detection
- Remove explicit width/height from render options - let phylotree.js
calculate dimensions using fixed-step spacing
- Use "left-right-spacing": "fixed-step" following the demo pattern
- Disable zoom to avoid potential coordinate issues
- Applied to both treeViewer.jsp and treeViewerInline.jsp

@hlapp Indeed, I may have jumped the gun on this one :) |
That's right -- Phylotree assumed that phylogenies without branch lengths had length=1 on every branch. But Phylotree should already fully support branch lengths in phylogenies. The Phylotree.js devs are very responsive -- I'd open up a new issue with them at https://github.com/veg/phylotree.js/issues if you're running into issues. Since December they've updated/fixed/improved a lot of their code (https://github.com/veg/phylotree.js/releases), so some older example code (including Klados) might be out of date. I can't really follow everything you're trying to do with Copilot, but I noticed that you were running into issues with the SVG node. Note that older versions of Phylotree.js were very closely tied to d3, so you had to set up a d3 SVG node (or something?) yourself and pass that to Phylotree. However, as of a year or so ago, Phylotree just needs a reference to a DIV node where it can create whatever SVG nodes it needs to. It's possible Copilot is using example code from an older version and getting confused. Klados' Phylotree.js code is overly complicated because it has to support highlighting clades after phyloref rendering, displaying multiple phylogenies on the same page and to update when the underlying phylogeny changes. But, if it helps, the key bits are:
