Version 1.0
Released May 25, 2004
Version 1.1
Released July 19, 2004
Fixed bug in shannon index files
expanded number of values to the right of the decimal point from 2 to 4
Version 1.2
Released August 23, 2004
Fixed bug in calculating variance of shannon index
Give user the flexibility to set the number of iterations to run
Reverted to presenting the mean instead of 50%tile for rarefaction curve
Fixed a small bug that had rarefaction curves going through (1,0) instead of (1,1)
Changed *.r_rarefaction filename to *.rarefaction
Changed *.r_*.ltt to *.ltt filenames (eg. *r_chao.ltt is now *.chao.ltt)
Wrote first version of user manual
Version 1.3
Released March 3, 2005
Final release before publication of paper in March 2005 issue of AEM
Fixed libraries dependency error that caused compilation problems on some platforms
Fixed core dump error received by some users
Fixed bugs in reporting Shannon & Simpson Indices
Changed number of places to report right of the decimal point for output files
Streamlined terminal output
Added user control of whether to calculate rarefaction curve for ecological parameters
(still calcuates traditional rarefaction curve) - makes execution much faster
Fixed some problems and updated parts of user manual
Version 1.4
Released March 8, 2005
Fixed bug in calculating the confidence interval for the Chao1 estimator
Version 1.5
Released April 19, 2005
Added 95% CI for ACE richness estimator
Updated bias-corrected Chao1 richness estimator and standard error formulae according to Colwell and Chao
Allow user to set largest distance to consider (-stop)
Allow user to construct a rarefaction curve obtained by sampling with replacement (-wrep)
Fixed a problem in constructing collector's curves caused by sequence names that are a fragment of another name
Version 1.51
Released April 22, 2005
Support mega3 formatted distance files as input
Version 1.53
Released November XX, 2005
Allow user to "jumble" the order of sequences in the distance matrix (use -jumble)
Allow the user to input a similarity matrix, although correction is still recommended (use -sim)
Modified data types in otu.h making the clustering procedure use less memory and faster
DOTUR now produces a file containing data to construct rank-abundance plots
