Import x and y values from the text file to jmp table

Hi,

Re: Import x and y values from the text file to jmp table and create wafer map

@jthi 
Just a quick question

The actual text file contains wafer information in the beginning. I want to store the data from row 21. I modified jsl as below. It does read as expected. Any suggestions?

			map_str = Load Text File();


			l = Words( map_str, "\!N" );
			rowc = N Items( l );
			colc = N Items( Words( l[21], "" ) ); //// edits

			dt = New Table( "Untitled",
				Add Rows( rowc * colc ),
				New Column( "X", Numeric, Continuous ),
				New Column( "Y", Numeric, Continuous ),
				New Column( "bin", Character, Nominal, Label( 1 ) )
			);

			For Each( {line, idx}, l,
				cur_rows = ((idx - 1) * colc :: (idx * colc - 1)) + 1;
				dt[cur_rows, "X"] = ((1 :: colc))`;
				dt[cur_rows, "Y"] = (J( 1, colc ) * (idx))`;
				dt[cur_rows, "bin"] = Words( line, "" );
			);

You should use some method to get only the wafermap (if you only care about it). Currently you are using the whole text file. Some options for that are

  • Regex
  • Substr with Contains
  • Words and split on {}
  • Words and split on row change and combine that with Contains to
  • hard coding lines and getting wafermap based on those (usually very bad idea)

Sorry to bother you again. I tried substr  but there's something not correct in the code. If you could modify, it would be great

			map_str = Load Text File();


			l = Words( map_str, "\!N" );
			rowc = N Items( l );
			colc = N Items( Words( l[21], "" ) ); //// edits

			dt = New Table( "Untitled",
				Add Rows( rowc * colc ),
				New Column( "X", Numeric, Continuous ),
				New Column( "Y", Numeric, Continuous ),
				New Column( "bin", Character, Nominal, Label( 1 ) )
			);

			For Each( {line, idx}, l,
				cur_rows = ((idx - 1) * colc :: (idx * colc - 1)) + 1;
				dt[cur_rows, "X"] = ((1 :: colc))`;
				dt[cur_rows, "Y"] = (J( 1, colc ) * (idx))`;
				dt[cur_rows, "bin"] = substr( line, 1 );
			);

You need to manipulate the string you get from Load Text File() in such a way that you end up with string which contains only the wafermap part of the text file. This won't give final string needed but gives one idea what you could do. See Scripting Index (and JMP Help) on how Substr and Contains work. It also has one option on using Words and Contains, which also needs some modifications to get correct list.

Names Default To Here(1);

demo_str = "SOMETHING
TEXT
EXAMPLE
MAP = {
.X.
XXX
.X.
}";

map_str = Substr(demo_str, Contains(demo_str, "MAP = {"));
show(map_str);

stop();
demo_list = Words(demo_str, "\!N");
map_start = Contains(demo_list, "MAP = {");
map_list = demo_list[map_start::N Items(demo_list)];
show(map_list);

Re: Import x and y values from the text file to jmp table and create wafer map

That's good explanation @jthi .

 

Quick question: 

The below statement will start reading data from second row of the list. I don't want to read the last row which contains brace "}".

How can I define the end line in the script

 

 

map_str = Substr(demo_str, Contains(demo_str, ".X."));

map_str = Substr(
	demo_str,
	Contains( demo_str, ".X." ),
	Length( demo_str ) - Contains( demo_str, ".X." ) -1
);

Note: Look in the Scripting Index for definition and examples for the Stbstr() function

Re: Import x and y values from the text file to jmp table and create wafer map

@txnelson ,

 

Your approach works if the pattern in the first row matches with the contain statement. I have several wafer maps which won't have same patterns. The only similarity is the wafer pattern starts at row number 21 in the text file. Is there a way to define the row number where the script will start reading?. I have attached a wafer map text file for reference (better view on note pad ++)

You could try Contains with "MAP = {". This should give you the location of "MAP = {" in the string and then use that knowledge with Substr to get what you want

Also check scripting index (and possibly JMP Help which you can open from Scripting Index) to understand how Substr (and other functions) work.
