Convert a file to PH
To convert other file formats to the "Bioinformatics & Development" file type, you need software like PHYLIP or a similar tool.
About PH files
The .PH file extension represents a significant source of ambiguity, as it serves two distinct, incompatible purposes in technical environments. Its primary function is storing phylogenetic tree data generated by the PHYLIP (Phylogeny Inference Package) software suite. These files contain evolutionary data describing the relationships between organisms, often formatted in the Newick tree standard. While scientifically valuable, raw .PH files are difficult to interpret without visualization tools like FigTree or Dendroscope. They are strictly text-based but rigidly structured, meaning a single formatting error can break compatibility with other bioinformatics tools.
Alternatively, a .PH file may be a Perl Header file. In the early days of the Perl programming language, these files functioned similarly to C headers (.h), containing code snippets or definitions included in other scripts. However, this practice is largely deprecated in favor of Perl Modules (PM), leaving .PH files as legacy artifacts that often trigger syntax errors in modern IDEs. Less commonly, .PH files are binary scene archives for Coktel Vision games from the 1990s, completely unreadable by standard text editors.
Conversion Best Practices:
For Research/Science: Convert PHYLIP data to NWK (Newick) or NEX (Nexus) to ensure compatibility with modern tools like MEGA. For publication or presentation, convert the tree visualization directly to PDF or SVG.
For Developers: Convert legacy Perl headers to TXT to safely inspect the code without execution, or refactor them into standard PM modules.
General Viewing: Since both primary formats are text-based, converting to TXT is the safest way to determine the file's contents.
Use Convert.Guru to open and convert your PH file.
If you want to convert PH file to POH, PKA, SGD, JS, TS, PY, JAVA, CPP, C, CS, PHP or RB, you can use PHYLIP or similar software from the "Phylogenetic Tree Data" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to PH, try PHYLIP or another comparable tool in the "Phylogenetic Tree Data" category.
The PH Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PH converter.
