The first line of the file, for example, looks like this:
"Montana","Algodonal","","","IV/54",1,1,1,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,36,11,19,1,1,1,0,0,0,0,0,0,3,1,1,0,0,0,0,0, 0,27,7,9,0,0,0,0,0,0,0,0,0,0,0,0
The first context analyzed belongs to the physiographic zone "Vega", "Algodonal" sub-community, there is no group nor structure. It belongs to the operation "IV/54". Then we have the numbers of obsidian and chert artifacts analyzed. There is 1 obsidian prismatic blade; 1 presents use wear, with a total of 1 independent use zone (IUZ). There are 0 obsidian macroblades; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian macroflakes; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian small percussion blades; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian Polyhedral core frag.; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian prismatic blade points; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian bifacial points; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian bifacial thinning flakes; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 36 obsidian flakes; 11 present use wear, with a total of 19 independent use zones (IUZ). There is 1 obsidian scraper; 1 present use wear, with a total of 1 independent use zones (IUZ). There are 0 obsidian notched flake; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian denticulates; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 3 obsidian flake cores; 1 present use wear, with a total of 1 independent use zone (IUZ). There are 0 chert bifacial points; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 chert bifacial thinning flakes; 0 present use wear, with a total of 0 independent use zone(IUZ). There are 27 chert flakes; 7 present use wear, with a total of 9 independent use zones (IUZ). There are 0 chert scrapers; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 chert denticulates; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 chert drills; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 chert choppers; 0 present use wear, with a total of 0 independent use zones (IUZ). The quotation marks around "Montana", "Algodonal" and "IV/54" indicate that these variables are alphanumeric and "" indicates the absence of data.
The last (28th) line is:
"Vega","PrincipalGroup","10L-1","10L-22","39/I/372",62,44,81,0,0,0,0, 0,0,1,0,0,0,0,0,0,0,0,1,1,1,0,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,1, 1,0,0,0,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0
Which indicates the physiographic zone "Vega", subcommunity "Principal Group", group "10L-3", structure "10L-22". It belongs to the operation "39/I/372". Then we have the numbers of obsidian and chert artifacts analyzed. There is 62 obsidian prismatic blade; 44 presents use wear, with a total of 81 independent use zones (IUZ). There are 0 obsidian macroblades; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian macroflakes; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 1 obsidian small percussion blades; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian Polyhedral core frag.; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian prismatic blade points; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 1 obsidian bifacial points; 1 present use wear, with a total of 1 independent use zones (IUZ). There are 0 obsidian bifacial thinning flakes; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 1 obsidian flakes; 1 present use wear, with a total of 1 independent use zone (IUZ). There is 0 obsidian scraper; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 obsidian notched flake; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 obsidian denticulates; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 obsidian flake cores; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 2 chert bifacial points; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 chert bifacial thinning flakes; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 chert flakes; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 chert scrapers; 0 present use wear, with a total of 0 independent use zones (IUZ). There are 0 chert denticulates; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 chert drills; 0 present use wear, with a total of 0 independent use zone (IUZ). There are 0 chert choppers; 0 present use wear, with a total of 0 independent use zone (IUZ). The quotation marks around "Vega", "Principal" and "10L-1" indicate that these variables are alphanumeric and "" indicates the absence of data.
