The MSU code is a line in the scantronformat.tab file located in
/home/http/lonTab that specifies the output format of the scoring file from
the scanning office. You probably can request your scanning office to
produce a specified output. The format of the line goes something like this:
#name:description:code
location:CODEstart:CODElength:IDstart:IDlength:Qstart:Qlength:Qoff:Qon:PaperID:PaperID
length:FirstName:FirstNamelength:LastName:LastNamelength
The fields have the following meaning: (column counts start from 1)
name - give this line a name like gwucode
description - this is what shows up in the drop-down menu like MSU Code,
but call yours GWU Code
code location - don't believe it is used in current version put -1
CODEstart - the column location where the anonymous exam code (6 letters) start
CODElength - the length of the code = 6 if using the 6 letters
IDstart - the column location where the student ID starts
IDlength - the length of the student ID
Qstart - the column location of the first question
Qlength - the length of each question - normally correspond to the number
of choices on the bubble sheet
Qoff - symbol for each bubble that is NOT bubbled, normally a blank space ' '
Qon - symbol for the bubble where the student has bubbled in - put say the
number 1
PaperID - the column location of the number for scanned bubble sheet -
printed by the scanning machine.
PaperID length - length of the paper ID
FirstName - column location of the first name
FirstNamelength - length of the first name
LastName - column location of the last name
LastNamelength - length of the last name
Here are some examples:
msunocode:MSU without any CODE:none:0:0:57:9:77:10: :1:5:5:51:1:41:10
msucode:MSU with CODE in separate location:letter:69:6:57:9:77:10:
:1:5:5:51:1:41:10
fsucode:FSU Randomized Exam Form:-1:47:6:54:9:80:10: :1:1:5:45:1:30:14
The output file from the fsu scanning office looks something like this:
00001 SMITHY N IJGGBH
111111111 1 1 1 1 1
00002 SMITHY K FECCJA
032345679 1 1 1 1 1
00003 DOE ASHLEY EBDEBB
