New commands
Feature updates
- changed the output for get.oturep names - http://www.mothur.org/forum/viewtopic.php?f=5&t=506&sid=b0e550aae63ff095ea48b51802a51526
- made minsnp=100 the default in chimera.slayer
- added groupmode parameter to summary.single - http://www.mothur.org/forum/viewtopic.php?f=5&t=513&sid=b44f89ef348ab38c197ffe489e656402
- added default option to set.dir, so that you can set input, output and tempdefault to the location of mothur's executable. This is helpful if you double click on the mothur executable, since current working directory will be set to your home directory.
- added countgaps parameter to chop.seqs command - http://www.mothur.org/forum/viewtopic.php?f=3&t=495&sid=4acb77fd1bf0275576c23be41e4ab8b5
- added summary and collect parameter to phylo.diversity - made summary=T the default and collect=F, rarefy=F by default. Summary=T creates a .phylodiv.summary file that contains the total phylogenetic diversity in each group.
- added scale parameter to phylo.diversity - phylo.diversity is divided by the number of sequences that have been sampled.
- added version numbers to all shortcut files mothur creates so they can be automatically remade when you upgrade to a new version.
- classify.seqs - when using knn method with distance search a .match.dist file is generated to report the smallest distance to the closest match in the database.
- added oldfasta and column parameters to dist.seqs - to append to a column-formatted distance matrix. given a column matrix, a new fasta file and a old fasta file we add distances to the original distance matrix calculated with the old fasta file.
- split.abund - if the rare or abund don't exist create a blank file anyway to prevent confusion when the command is run multiple times.
- made neighbor=T default in clearcut
- added fontsize and numotu parameters to heatmap.bin command. Also added more sorting options for the picture: none, shared, totalotu, totalgroup. - http://www.mothur.org/forum/viewtopic.php?f=5&t=504&sid=3ea797594a02a1bdbc0972a7120b9919
- increased speed of parallelized commands file division.
- new calculators:
- invsimpson - the inverse Simpson index (1/D)
- simpsoneven - a Simpson index-based measure of evenness
- shannoneven - a Shannon index-based measure of evenness
- heip - Heip's metric of community evenness
- smithwilson - Smith and Wilson's metric of community evenness
- Added "[ERROR]" to the start of every error message that is outputed to the logfile to make it easy to grep errors from large logfiles.
- screen.seqs no longer outputs *bad.fasta, *bad.names, *bad.groups
- heatmap.bin can now take a relabund file as an input.
- added relabund parameter to read.otu command.
- added clearcut source to mothur so that clearcut exe is no longer needed.
- increased speed of unifrac commands, changed default of random parameter to false.
Bug fixes
- fixed bug with venn command if no valid calculators are given.
- fixed bug with collect.single, rarefaction.single and summary.single when run in shared mode after one another the second command would only output results for last group.
- deleted .names.temp that was left behind on windows version.
- changed classify.otu to assume the list file contains all sequences instead of just uniques.
- sffinfo trimming first base.
- classify.seqs was adding an extra unclassified at the end of all classifications.
- phylo.diversity - the collect and rarefaction data seems to suggest that each group being analyzed has the same number of sequences - the total number of sequences. It should instead be the number of sequences in each group. So if the largest sample only contains 1000 sequences it should only go down 1000 sequences, not the total number of unique sequences across all groups.
- fixed bug that did not apply hard to cutoff output of cutoff change in cluster.split and cluster.
- fixed bug that occurred with some of the calculators that caused negative results if the numbers were larger than the largest possible int for a given platform.
- fixed ambiguous output for align.seqs flip=T. - http://www.mothur.org/forum/viewtopic.php?f=4&t=533&sid=3ea797594a02a1bdbc0972a7120b9919
- fixed bug that truncated accession names in mpi-enabled version if a file with Windows line endings was used. - http://www.mothur.org/forum/viewtopic.php?f=4&t=492&p=1174
- modified pre.cluster to make it faster
