Good Morning Archie: Please note the difference in data value resolution between the values you obtain from the .wib files with hgWiggle, and the original ascii data values you find in the wigFix files. Note the "Known issues section:" at http://genomewiki.ucsc.edu/index.php/Wiggle
hgWiggle is the convenient query mechanism to work with the wiggle data sets with the caveat of the loss in resolution of the data values. And yes, it can work on whole chromosome, or even whole genome queries. The original ascii data files have the non-lossy data values, but they are simple ascii data files with no indexing available to allow convenient access. If you have a spread sheet or R system which can handle a couple billion numbers in one table, you could perhaps throw all those numbers into that system. I'm not familiar with what procedures you would use there to manipulate such a set of numbers. See also: http://genomewiki.ucsc.edu/index.php/Using_hgWiggle_without_a_database You could convert the wigFix files into bigWig files to avoid the loss of resolution. However, the query utilities into bigWig files are going to return ascii data values, or summaries in regions. You would again need to manage the returned ascii data values.
