WebApr 20, 2024 · 2. I have used multiple sequences aligned file of protein data to generate a maximum parsimony tree, then I used the "bootstrap_trees (msa, times, tree_constructor)" function from biopython to generate bootstrap replicates of my MSA data. I have my original tree and bootstrap replicates for my tree, I want to ask how do I compare the topology ...
WebSep 10, 2024 · I'm trying to plot a simple distance tree of my blastn output with nj (like the tree view on NCBI). From what I understood, what I think I should do is. extract all the hsps from each alignment. re-align them using MUSCLE. generate a distance matrix from the msa file. plot the tree using nj. However, there is a couple problems I am not sure about: WebJul 10, 2024 · Bootstrap is sampling method. Main thing is that how do you sample the data. bootstat = bootstrp (nboot,bootfun,d1,...)
