this online tool) but those listed above are the ones that I am most familiar with.Step is to open Excel and find the sequence column. There are a lot of other options out there (e.g. This is the path I usually take for file conversion with large datasets. A search for 'Perl convert fasta nexus' brought me to this script, and 'python convert nexus phylip' took me here. A simple google search reveals many, many existing scripts for file format conversion in several different languages. However, I'm a ninja when it comes to finding other people's code online and tweaking it when necessary. I'll be honest: I'm no good at writing code. The PGDSpider website notes that it is not capable of handling large NGS datasets, which may make this final option more appealing: It can parse 31 and write to 34 different file formats. It's not quite as simple as ALTER, but it's also much more powerful in terms of the number of file formats it can handle. 'PGD' stands for Population Genetics Data, so many of the file formats are common to population genetics data (microsats, SNPs, etc.) and software (Arlequin, Structure, etc.). PGDSpider is a powerful java-based tool for file conversion that can be run either from command line or a GUI. My only complaint is that the site goes down pretty frequently, so it's good to have one of these other options up your sleeve: The converted file will download automatically to your computer.ĪLTER is incredibly easy to use, completely free, and does not require a software download. Simply upload your alignment file, select your output format, and convert.

This online tool can convert alignment files to and from the following formats: NEXUS (.nex), Fasta (.fa or. Here are my top choices:ġ) ALTER (ALignment Transformation EnviRonment) Instead, I like to use tools or scripts that automate the process. Manually editing and converting among these file formats is easy enough to do, but it's also time consuming and may introduce human error. MrBayes requires nexus files, PhyML and RaxML require PHYLIP, many other programs need fasta files (just to name a few).

When I'm working with a dataset for phylogenetics, I often need to convert among different file formats.
