I am just starting with phylogenetic trees. Does anyone know a free and not too complicate online platform for creating such trees? I have got environmental samples from biofilms.
Use ClustalW (http://www.ebi.ac.uk/Tools/msa/clustalw2/)for construction phylogenetic tree. first step do multiple sequence alignment, then construct tree.
To create a phylogenetic tree you will need DNA sequence data from your samples. Once you have extracted the DNA and sequenced it, you can align the sequences for comparison and use that information to create a phylogenetic tree. I have had good luck with the MEGA series of programs for this purpose (http://www.megasoftware.net/).
You won't find to many online platforms but you could try this (no experience though): http://www.phylogeny.fr/
I would recommend you to do the work locally, but this then depends on what platform you are using, but here is a link to a previous post that has all the points you need to get a "publishable" tree: https://www.researchgate.net/post/How_do_you_align_DNA_sequences_for_phylogenetic_work_What_is_the_order_of_events_and_what_software_do_you_use
Hello, while the establishment of phylogenetic tree from DNA sequence is commonly described in books and webdocuments, I'm fighting with another case. Could someone explain how to proceed to build tree diagram with Mega5 or mega6 starting from an Excel-generated matrix of genetic distance computed from SNP or SSR genotyping data ?
