CSD
Corrections 1.40 is an indirect, distribution-free method for
stereological corrections of Crystal Size Distributions determined from
measurements of crystal outlines in thin section, outcrops etc. The methods
it uses are described in Higgins (2000, 2002, 2006)
Please tell me if you find any bugs.
CSDCorrections runs on the Windows Operating System. It runs properly under
Parallel Desktops, which is a version of Windows software
on a Mac. It runs on most installations of Wine or Virtual
Box (in Linux) or Virtual Box (Mac).
It is well integrated with the free image processing program ImageJ.
If you have already installed ImageJ then a macro will be installed to help
transfer the data from IMageJ to CSDCorrections. See the guide
here.
Version History
Version 1.4.0 (August 2012)
Calculates and displays orientation data
Calculates and displays "Big R" crystal position distribution
parameter.
Can handle 20 000 points in each data set
Minor layout changes
New version of ImageJplug-in will transfer length, width, area, angle, centroid X,
centroid Y, notes data to .csd file.
Minor bug fixes - mostly concerned with second data set
Bug fixes - occasional failure to start (1.4.0.1)
Minor layout changes to regression data table (1.4.0.1)
Minor bug fixes (1.4.0.2 - September 2012)
Improved rose diagram for orientations (1.4.0.2)
Version 1.3.9
Significant bug fix. An error in the population density values was
introduced with version 1.37. This only affected prismatic crystals.
They were overestimated by a factor of I/L. For example, if S:I:L =
1:2:4 then ln(pop den) was 0.7 ln units too high. All other parameters
were unaffected.
Minor changes in program layout.
Minor bug fix – range in characteristic lengths (1.3.9.2).
Minor bug fix – popup menu / 'copy all' in raw data (1.3.9.3). (August
2011)
Several minor bug fixes - decimal separator and raw data tables
(1.3.9.4). (August 2011)
Minor bug fixes - sorting of raw data (1.3.9.5). (November 2011)
Version 1.3.8
Minor bug fixes.
New 2D data display - length, width and area are all in one
table.
Easier to compare calculations from intersection length and width.
New version of ImageJ plug-in
will transfer all three data columns to .csd file.
Volume % calculated from intersection areas, if present.
Intersection width / intersection length of sample and model can be
compared easily.
New save / load dialogue boxes.
Plots of intersection width / length use fixed number of points in
each bin (see Higgins and Chandrasekharam, 2007)
Minor bug fixes. (1.3.8.2)
Notes now on first page (1.3.8.2)
Width/length, etc graphs now with results. (1.3.8.2)
Saving and loading of bins-pers-decade bug fixed. (1.3.8.3)
Second data set can be loaded from a second .csd file (1.3.8.3).
Version 1.3.7
New page format - Input and output data clearly separated
Choice of four output graphs and tables:
'Classic' ln(population density) vs size
Cumulative distibution function (lognormal)
Power Law (Fractal)
Simple population density histogram
Correction of CSD to known volumetric phase abundance (see Higgins,
2006)
Automatically checks for new version on start-up
Can handle 10 000 points (1.3.7.1)
Fixed 'copy' problem of several data tables (1.3.7.1)
Only checks for a new version once a week (1.3.7.1)
Numerous minor bug fixes (1.3.7.1)
Version 1.3.6
Corrections of several bugs
Reads damaged files more easily
New XML file format - easier for further expansions of method
Version 1.3.5
Custom and linear size bins possible
Other intersection size definitions possible - maximum length and
ellipse dimensions
Graphs of aspect ratio and normalised intersection length/width
Possible to select scale of graph
Data format is slightly different, but can read old formats.
Version 1.3 - 1.3.2
Uses a new, accurate algorithm for calculating intersections of a
triaxial ellipsoid
Uses a new algorithm for interpolating between a block and an
elipsoid, for rounded crystsls
Has the capacity to treat 2 data sets gathered at different
resolutions
Can use bins per decade or phi bins
Can add notes on each sample.
New style with 'pages'.
Uses a new file format. All processing parameters are retained now.
Old files (version 1.1, 1.2) can be read by version 1.3.
Copy and paste more extensively implemented - even graphs. Just
right click.
You can choose which points to plot. Just click on the plot box.
A regression weighted for the errors in each point is performed.
(Version 1.3.1)
Minor bugs corrected -- Version 1.3.2
Version 1.2
Calculates volumetric phase proportions. This is useful for verifying
that CSDs have been calculated correctly and other purposes (Higgins,
2002).
