lexa

Tue Jul 19 00:00:35 MST 2005


this directory and subdir were written ca 1991-2 to analyze john little's
lab's data on cleavage of lexa as a function of pH

rate law modeled and fit to data with simplex algorithm

top directory (this directory) has the  Makefile to generate the two
modelling progs: lexafitB and lexafitken (for a stripped down model)

see lexafitB.c and lexafitken.c for brief description of model
see README* filles for more details

----------------------------------------------------------------------

usual mods to port to macosx = 
	makefile cflags
	in awk scripts, nawk->awk, and relocate cli vars if present
	and not much more

crude plots with ttygraph, using the local *prep etc scripts of this dir,
work nicely

agreement of results under macosx and sgi = decent to excellent 
	the multiparameter fits can have a flat minimum -> large effect of
	small differences in precision/less significant digits


to test progs:
	go to lexa/results.B, for lexafitB
		runallB 1
			runs lexafitB on datafile.1
			to produce outfile.1
			and plotfile.1
			view results with:
				vi *.1
				(see results file, then crude plot)
		lexa/results.B/0-Old 
			directory with files produced under sgi in 1990's

	go to lexa/results.B.corr, for testing lexafitken and lexafitB
		same as above for lexafitB

		have to run lexafitken "by hand"; also, no ttygraph plots

		agreement excellent with 0-Old 1990's results

the *data* *out* and *plot* files in lexa/results.B* directories were
used/generated under macosx and can be compared to corresponding files
under the 0-Old directories below them
