PaleoMag 3.1 for Macintosh, Windows and Linux

***WARNING***

Version 3.1b1 apparently has some bugs in the feature allowing edited samples to be saved. Please be aware of this and either do not use this feature or only use with caution. PaleoMag was originally written as a non-editing code to avoid this; we suggest only using PaleoMag on a copy of your data in case of difficulty. Some issues are also reported with the Common Means statistic. Finally, we have one report of a serious crash running under Mac OS 10.5 with Parallels running. While this might be a coincidence, if you experienced something similar, please let us know.

This might be corrected in 3.1b2, where a bug in outputting binary 2G format files was corrected. PLEASE let me know if any issues are still present, and be sure to double check anything edited.

14 June 2009. 3.1b2. Fixed bug where internal change for 2G formats from mass to volume led to an overlong string being output which makes the new output file useless. Compiled now with RealBasic 2009r1.

The old (pre-modern memory manager) version 2.3 is still available.

Version 3.1 is closed to new features. We will then shift to developing 3.2, which will start with replacing both the input and output core of the program and replacing the core graphics approaches, both of which have gotten inefficient as we have added more formats and more plots. This will allow us to better address other formats such as the MagIC database and the multiple magnetometer formats. We will maintain 3.1 for any reported bugs.

24 October 2006. 3.1b1. (Several internal builds absorbed 41 and 42). Fixed bug in "reverse" function in confirming an LSQ fit made with the menu command (instead of out of the current fit window). Added contextual menus to the sample list and LSQ list windows allowing show/hide and (in LSQ) reversal of direction. Added Non-parametric ("Watson") statistics. Other changes too (will update later).

14 October 2005. 3.1d40. Fixed bug in editing 2G files (this also meant we've expanded internal representation of samples to include all the 2G fields).

15 September 2005. 3.1d39. Fixed bug in 38 reading Means files. Added link to the QuickGuide as help.

12 September 2005. 3.1d38. Adds ability to change the magnetic declination for CIT format files. This is a pretty profound change and will not propogate to any means files made from the uncorrected data. Added a Common Means test for mans selected from a Means window (in the statistics menu).

4 February 2005. 3.1d37. Fixes for black screens when using 2G format data. Spherical standard deviation added to Fisher statistics. Symbol shape can be customized for LSQ EQ area window directions (through the Edit menu from the Least Squares List window). Fixed failure to quit when LSQ windows (only) are used and locality bedding was calculated (should also fix failure to quit when .SAM file was changed but locality list window is hidden). Fixed error in calculating a direction from a pole position added to the Means file.

11 October 2004. 3.1d36. Minor fix for wrong colors for site equal area window.

9 October 2004 3.1d35. Miscellaneous fixes. Added ability to add mean directions from an existing pole or reference direction. Modern day axial dipole field can be displayed on equal area plots. Reversal test now will use plane data as currently specified as in the equal area plot from which reversal test is called (as planes, best point on plane--which is kind of a questionable test--or best point on arc).

8 June 2004. 3.1d33. Adds labels and user-controlled symbol sizes to equal area and orthographic plots, also improving their print quality. Means legend now printed for LSQ EQarea plot, and several new symbols are added. A threshold now hides high-MAD measurements when a sample is first opened. Copy/cut/paste added to sample list window. Several other smaller improvements.

25 May 2004. 3.1d32. Adds clear (in the Edit menu) for LSQ list window. Fixes (finally!) the missing display of statistics in the LSQ Equal Area window. Fixes bug where selecting "LSQStrat Window" from the menu while that window was open would crash the program. Sorting in the LSQ window and Locality window both use numerical sorting of sample numbers instead of the old lexical sorting. Added check when saving LSQ from Current Fit window to see if the id matches an existing ID. Allows for replacing that id. Deleted a potential bug that could have caused some info added to LSQ fit window to be a pile of duplicates of the same fit (not seen in practice, but the potential appears to have existed).

18 May 2004. 3.1d31. Changes Edit behavior to only change the version in memory; saving is now at the user's discretion. "Dimples" in red dot (close button) for OS X implemented in Sample List, Site, LSQ, and Means windows. Bug where sample magnetic declination was not being copied fixed (might have affected some things with 2G format, though we don't think so). First build with RealBasic 5.5; first Linux version.

14 May 2004. 3.1d30. IMPORTANT BUG FIX: All versions from 3.1d26 to 3.1d29 have a bug when editing two or more different samples from the same List window (this happens when you use the next or previous sample command). All edits after the first will save the first edited sample's data into the other sample files. You can recover the original data by going into the locality directory and removing the newly created files and then renaming the "-old" versions of the files to their original names. This version (d30) fixes this bug by making the Edit Sample window modal. We also added a warning that the least squares fits are NOT corrected for edits made to the sample. We will be revising the code a bit more to make the save of the edited data to be at the user's request and not automatically as is done now when you accept your changes in the Edit Sample window.

17 November 2003. 3.1d29. Fixed numerous problems with magnetic declination not being propagated properly. 2G files now use local (sample specific) magnetic declination. Autofill of missing core or tilt-corrected directions now uses magnetic declination. Magnetic declination shown in sample info pane in sample list window (since can vary from sample to sample). Edit Sample dialog fixed up to permit viewing either in magnetic or true north coordinates, also to permit the directions to be recalculated from a specified direction type (core, geographic, or stratigraphic). We still do not support fold axis plunge corrections, so use the editing options with care (you'll lose any corrections that used a fold axis plunge if you edit directions). Incorrect hemisphere for core coordinate equal area plot fixed.

16 November 2003. 3.1d28. Fixed some bugs with Edit Sample. Autofill CIT format files missing core and/or tilt-corrected directions. Reversal test added (if someone has a good check case, especially for the bootstrap code, we'd like to have it). WARNING: It appears that there is a bug in the Edit Sample dialog that requires entry of core plate strikes and bedding strikes in magnetic coordinates. We'll try and get this fixed ASAP--there are some inconsistencies in the manner in which things are dealt with in the code.

5 September 2003. 3.1d27. PC fixes to cure crash when opening a sample file. Font in Sample List window set to Terminal font on PC. Keyboard shortcuts for next/previous sample set to J and K instead of + and -.

2 September 2003. 3.1d26. Lots of fixes and updates. Added ability to edit .SAM file and core and bedding orientations within PaleoMag (However: although you can change the magnetic declination, this is not carried through to all places it should until version d38. For instance, CIT format stores bedding and core orientations relative to magnetic north, which means that a change in magnetic declination should change geographic and tilt-corrected directions, and any least-squares fits from these. These changes are not, at present, done). .SAM files created for non-CIT formats. Strat plot enabled for non-CIT formats (only extensively tested for 2G binary (.DAT) format, so feedback welcome). Several interface bugs fixed.

How to help

Of course crashes are useful. If you use the code and test it, please note the machine, system software version, whether you were using your normal extensions or not. If you encounter crashes, note what you were doing, what windows were open, and just what happened after your last action (did a dialog come or go, etc) and any error code reported. The most likely problems will be out-of-memory errors as I have not put in place all the checks to assure that there is enough memory; you can try giving the code more room and seeing if the errors reproduce.

Please get back to me even if you have no problems. It might be most helpful to know that the code is ok. If I hear nothing, I might just decide that you all have Matlab scripts or Excel macros that you prefer.

Citation. Well, there is now something you can cite if you use PaleoMag in research publications:

Jones, C. H., User-driven Integrated Software Lives: “PaleoMag” Paleomagnetics Analysis on the Macintosh, Computers and Geosciences, 28 (10), 1145-1151, 2002.

Thanks for your patience. It has been a far longer road than I would have liked.

Specific issues at present

• Common Mean statistic reportedly erratic.
• No interaction with points in strat plot (select/deselect must be from list or LSQ EQarea)
• Loading LSQ file now seems awfully slow (fixed in d31?)
• Locality EQArea window needs statistics
• Colors in Strat plot not customizable (and not very good either)
• Strat plot limited to 3 panes
• Core direction not supported in Strat plot
• Does not show the ranges of an arc on Strat Plot.
• Improving printing to use the highest resolution on printers (Strat plot uses this)
• Statistics keeps vanishing from the pane at the top of the LSQ EQarea plot. (fixed in d32?)
• Get rid of double drawing (or worse) of LSQ EQarea plot when changing a selection
• Old error ellipses remain on plot sometimes in LSQ EQarea plot (can resize image to eliminate them)
• No labels for arcs (would be nice for arcs to not need poles on plot)
• Crashes on close (?--we don't see, but reported)
• Drawing needs to be totally revamped to cut out clumsy refreshes and slow response time

To do (sort of prioritized)

• Edit data safely (MOSTLY DONE)
• Finish getting Means file used (including VGP stuff) (DONE except VGP)
• Locality equal area plot (MOSTLY)
• Add stratigraphic plot (MOSTLY)
• Import/export, including all versions of 2G and MagIC (IN PROCESS)
• Copy/cut/delete from LSQ list window (Delete added, d32)
• Add new means/VGPs manually (so can show a reference direction) (DONE)
• Add Watson (non-parametric) statistics (DONE)
• Add printing sample IDs on side of strat plot
• Add tilt correction with fold axis
• Save layout in preferences (allow opening a sample to open multiple windows)
• Add sites from samples
• Locality strat plot
• Clean up annotations, J/J0 plot and Locality EQ area.
• Clean up zooms
• Multi-plot printing
• Print a zoomed view properly
• Window list, bring all to front command (Mac)
• Add lines/points showing current fit on Orthographic and EQarea plots
• Add dual geo and strat points to EQarea plot
• Add traditional J/J0 plot (against my advice...-this isn't a very helpful tool IMHO)

• Fixed poor graphics on strat plot (but still a workaround for a RealBasic bug)
• Added Copy Special to Strat Plot to allow user to copy figure to clipboard with a specified strat interval/cm of plot.
• Added Edit Sample and Edit Locality options (Note that magnetic declination is allowed to be edited but should be treated with caution: many formats use this to correct the stored orientation of the core.
