Even better would be to leave the sign in the value for the setDiff 
method. Only use abs to look for the difference with the value in the 

float diff, searchdiff;

searchdiff = [diffinput floatValue];	// need to add a inputfield in the 
diff = mw-theweight				// distance from target mw

	if (fabs(diff) <= searchdiff )
		[peptide setDiff: diff];
		[peptide setRange: aRange];
		// add it to the results array, release it to counterbalance the init 
as it is now retained by the array
		[results addObject: peptide];
		[peptide release];

		// yep, we have another one screened:
