Function

Bootstrapped discrete sites algorithm

Description

Reads in a data set, and produces multiple data sets from it by bootstrap resampling. Since most programs in the current version of the package allow processing of multiple data sets, this can be used together with the consensus tree program CONSENSE to do bootstrap (or delete-half-jackknife) analyses with most of the methods in this package. This program also allows the Archie/Faith technique of permutation of species within characters. It can also rewrite a data set to convert it from between the PHYLIP Interleaved and Sequential forms, and into a preliminary version of a new XML sequence alignment format which is under development

Algorithm

SEQBOOT is a general bootstrapping and data set translation tool. It is intended to allow you to generate multiple data sets that are resampled versions of the input data set. Since almost all programs in the package can analyze these multiple data sets, this allows almost anything in this package to be bootstrapped, jackknifed, or permuted. SEQBOOT can handle molecular sequences, binary characters, restriction sites, or gene frequencies. It can also convert data sets between Sequential and Interleaved format, and into the NEXUS format or into a new XML sequence alignment format.

To carry out a bootstrap (or jackknife, or permutation test) with some method in the package, you may need to use three programs. First, you need to run SEQBOOT to take the original data set and produce a large number of bootstrapped or jackknifed data sets (somewhere between 100 and 1000 is usually adequate). Then you need to find the phylogeny estimate for each of these, using the particular method of interest. For example, if you were using DNAPARS you would first run SEQBOOT and make a file with 100 bootstrapped data sets. Then you would give this file the proper name to have it be the input file for DNAPARS. Running DNAPARS with the M (Multiple Data Sets) menu choice and informing it to expect 100 data sets, you would generate a big output file as well as a treefile with the trees from the 100 data sets. This treefile could be renamed so that it would serve as the input for CONSENSE. When CONSENSE is run the majority rule consensus tree will result, showing the outcome of the analysis.

This may sound tedious, but the run of CONSENSE is fast, and that of SEQBOOT is fairly fast, so that it will not actually take any longer than a run of a single bootstrap program with the same original data and the same number of replicates. This is not very hard and allows bootstrapping or jackknifing on many of the methods in this package. The same steps are necessary with all of them. Doing things this way some of the intermediate files (the tree file from the DNAPARS run, for example) can be used to summarize the results of the bootstrap in other ways than the majority rule consensus method does.

If you are using the Distance Matrix programs, you will have to add one extra step to this, calculating distance matrices from each of the replicate data sets, using DNADIST or GENDIST. So (for example) you would run SEQBOOT, then run DNADIST using the output of SEQBOOT as its input, then run (say) NEIGHBOR using the output of DNADIST as its input, and then run CONSENSE using the tree file from NEIGHBOR as its input.

The resampling methods available are:
