I'm looking for software for illustrating tree diagrams am wondering whether anyone knows which was used to create the one in the post linked below.
I have tried messaging the author, but had no luck and was wondering whether someone recognized the application used or maybe has suggestions for others.
Post: Analyzing negation with a syntactic tree
Example tree:
This is almost certainly done with LaTeX, or one of its friends, and the tikz-qtree package. It is an improvement of the qtree package with nicer node placement. If you are not familiar with LaTeX, and want to learn more, this Wikibook might help (link is to the page about linguistics, but the book is in general about LaTeX). Both tikz-qtree and qtree have a quite extensive manual.
Below is LaTeX code using the tikz-qtree package to draw your tree. The only difference with the original seems to be that the bar over the T and the v is less bold. Perhaps this was done with something like this, but I cannot get it to look exactly the same.
\documentclass[margin=5mm]{standalone}
\usepackage{tikz-qtree}
\begin{document}
\Tree [.TP
[.NP Jane$_i$ ]
[.\=T
[.T did T(past) ]
[.NegP
[.Neg not ]
[.vP
[.NP t$_i$ ]
[.\=v v [.VP \edge[roof]; {go to school} ] ]
]
]
]
]
\end{document}
An older version of this answer just used the qtree package (instead of tikz-qtree) and draws something that looks like your tree. The only trick we need is to use array and \setlength{\extrarowheight}{2pt}, because otherwise the bar over the T is touched by the edge. The differences with the original:
\documentclass[margin=5mm]{standalone}
\usepackage{qtree}
\usepackage{array}
\setlength{\extrarowheight}{2pt}
\begin{document}
\Tree [.TP
[.NP Jane_i ]
[.\=T
[.T did T(past) ]
[.NegP
[.Neg not ]
[.vP
[.NP t_i ]
[.\=v v \qroof{go to school}.VP ]
]
]
]
]
\end{document}
\overline{\text{T}}, though \={T} is simpler.

If you want a VISUAL editor for Syntactic Trees, I think TreeForm could be a solution for you. The software is a specific solution for drawing Trees in a WYSIWYG approach. It has "templates" for X-Bar 3 levels (XP-X'-X), adding adjuncts/complements, etc, all with one click and some typing (actually, not literally a click, you drag and drop models/phrases and add them to the tree).
The software has several possible improvements and limitations, but it works. I have actually found this thread while looking for a better solution, but meanwhile it's the best thing I know about (considering my preference for a visual editor).
