PREFERENCES...
, This window lets you select your preferences for program appearance and functions. Chose one of four tabbed categories: Appearance, Sounds, Fonts, Plots, File Handling, and Operations.
File opening options: When selecting a file to open, you can access Warthog-format files only (this includes Sable files), or access any file type, including .text or .csv files.
Warn before closing or quitting: This option, if selected, will warn you if you are about to perform an operation (closing a file or quitting) that will destroy work you have performed on the current file.
File filtration: This option, if selected, checks newly-opened files for abberant readings ('spikes') and fixes them. It only handles single values that differ from both the immediately preceding and immediately following values by 400 or more.
File appending: When you append a file to an already-loaded file, the program normally shows the channel labels in each of the files and asks your permission before proceeding with the merge. If this option is selected, appending will occur 'automatically' (without asking the user) IF the number of channels is the same in both files. Note that it does not matter if the channel labels differ..
To avoid having to re-set your preferences at every launch, click the ‘Save Current Preferences’ button to store your current settings (including screen colors, current values of FiO2, FiCO2, and RQ, etc.) in a file called ‘LAprefs’. When launched, LabAnalyst looks for this file and reads the preferred settings from it.
Caution: You’ll get unexpected results if you use an ‘LAprefs’ file made with a Power-PC Mac on an Intel Mac, or vice versa. This is because numeric data – such as in the preferences file -- are stored in two formats: ‘big-Endian’ and ‘little-Endian’. Endian-ness is a property of the CPU. Power-PC processors are big-Endian; Intel processors are little-Endian. If you record your preferences on a PPC Mac and then read them on an Intel Mac (or vice versa), you'll get unpredictable results, manifested most obviously as weird screen colors.
