    1: \label{Domain_Configuration_Scantron_Format}
    2: Where scantron exams are used in a course, the format of data in the
    3: file generated from the processing of bubbled-in scantron sheets may
    4: vary between institutions. The format definitions available when performing
    5: scantron grading in LON-CAPA were originally listed in the scantronformat.tab
    6: file, stored in /home/httpd/lonTabs, which might have been modified
    7: locally on each server. 
    8: 
    9: Starting with LON-CAPA 2.7, scantron format information is read from
   10: either a custom.tab file, or a default.tab file both of which belong
   11: to the special domain configuration user (\$dom-domainconfig, where
   12: \$dom is the name of the domain) and which are automatically published
   13: into resource space. 
   14: 
   15: For LON-CAPA installations older than 2.7, when the primary library
   16: server for the domain has been updated, a Domain Coordinator should
   17: display the \char`\"{}Scantron format file\char`\"{} configuration
   18: page via \char`\"{}Domain Configuration\char`\"{}. The first time
   19: this page is displayed, a default.tab (a copy of the standard LON-CAPA
   20: scantronformat.tab file), and a custom.tab (if the scantronform.tab
   21: file currently on the server differs from the standard file) will
   22: be copied and published. Thereafter any changes to scantron format
   23: files to be used for grading scantron exams in courses from the domain
   24: will be made via the Domain Configuration menu. Any scantronform.tab
   25: files in /home/httpd/lonTab directories on servers in the domain will
   26: no longer be used.
   27: 
   28: The settings available via \char`\"{}Scantron format file\char`\"{}
   29: support upload of a new custom file, or deletion of an existing custom
   30: file (in which case grading will default to use of the default.tab
   31: file). An uploaded scantron format file contains one or more lines
   32: of colon-separated values for the parameters in the following order:
   33: 
   34: {\scriptsize name:description:CODEtype:CODEstart:CODElength:IDstart:IDlength:Qstart:Qlength:Qoff:Qon:PaperID:PaperIDlength:FirstName:FirstNamelength:LastName:LastNamelength} 
   35: 
   36: \begin{itemize}
   37: \item name is the internal identifier used within LON-CAPA
   38: \item description is the text displayed for each option in the   
   39: the {}``Format of data file'' dropdown in the Scantron grading
   40: screen.  The user will choose the appropriate format for the scantron
   41: file currently being used for scantron grading.
   42: \item CODEtype can be either 'none' 'letter' 'number' 
   43: \item Qon can be either:
   44: 
   45: \begin{itemize}
   46: \item the symbol that says a bubble has been selected, or
   47: \item 'letter' (for when the selected letter appears), or 
   48: \item 'number' for when a number indicating the selected letter appears 
   49: \end{itemize}
   50: \end{itemize}
   51: As an example, below are four different format lines: the first two
   52: were used at MSU prior to 2006; the last two have been used since
   53: then.
   54: 
   55: \begin{itemize}
   56: \item msunocode:MSU without any CODE:none:0:0:57:9:77:10: :1:5:5:51:1:41:10 
   57: \item msucode:MSU with CODE in separate location:letter:69:6:57:9:77:10:
   58: :1:5:5:51:1:41:10 
   59: \item msucodelet:MSU with CODE in separate location (letter format):-1:69:6:57:9:77:1:
   60: :letter:5:5:51:1:41:10 
   61: \item msucodenum:MSU with CODE in separate location (number format):-1:69:6:57:9:77:1:
