Hello, have not being able to figure out how to do this on my own so I am wondering if anyone here can help me.
Is it possible for multiply block lists to load from a single file randomly yet never repeating the same item in the file twice in any of the blocks across the whole study?
faithfully
Joel

| If what you mean by this is that you have a file with 100 entries and then you have four different block lists that will each run 25 rows but you want to make sure that if BlockListA samples row 37 that BlockListB will not also sample row 37, then the easiest way I can think of doing this would be as follows... 1) Create one master list that loads from the file and stick in unreferenced. Set to random, sequential, etc
2) On all of your other lists, specify the name of this List in Nested column. That is basically it. By setting the Nested List, you inherit all of the attribute columns from the nested list. And each list will ask from this master pool ensuring that the row is only selected once until it runs out of exemplars and is reset. -Brandon

Dear Brandon
Thank you for your prompt reply, just one more quick question, how is the txt file formated? In the book it says that it needs to have attribute data and be tab-delimited but having slight trouble with the exact layout, ie dont have a clue :-)

| Pop open Excel and place the column headings in the first row (Weight, Nested, Procedure, Attribute1, Stimulus, CorrectAnswer, etc). In subsequent rows, place your list data. When you save the workbook, choose Tab Delimit *.txt. If you are using E-Prime 2.0, you can also choose "XML Spreadsheet *.xml" and specify that file too. If you don't have Excel, then using Notepad, take care in using the tab key inbetween each column entry. -Brandon
