NAME

       auto-multiple-choice-note - computes marks after scans data capture for AMC multiple
       choice exams.

SYNOPSIS

       auto-multiple-choice note --data project-data-dir [--seuil threshold]
                            [--grain granularity] [--arrondi rounding] [--notemin min]
                            [--notemax max] [--no-plafond | --plafond]

DESCRIPTION

       The auto-multiple-choice note command computes marks for all students from the scoring
       strategy extracted from the LaTeX source file by auto-multiple-choice-prepare(1) and from
       the data capture reports made by auto-multiple-choice-analyse(1).

       --data project-data-dir
           gives the directory where data files are (see for example auto-multiple-choice-
           meptex(1)).

       --seuil threshold
           gives the black ratio threshold for deciding whether a box is ticked or not. When
           deciding whether a box is checked or not, auto-multiple-choice note compares the black
           ratio (number of black pixels over total number of pixels) to threshold. If the black
           ratio is greater then threshold, the box is declared to be checked. Standard values
           can be 0.15 in the standard layout, or 0.5 for separate answer sheet layout (in this
           last case, letters are drawn in the boxes, and the students are told to fill the boxes
           entirely).

       --seuil-up upper_threshold
           gives the black ratio threshold over which a box is considered as not being ticked.
           You can set this value to (for example) 0.6 to allow students to cancel a ticked box
           filling it completely: if the black ratio is between threshold and upper_threshold,
           the box is considered as being ticked, but if the black ratio is greater than
           upper_threshold (for example when the box is filled), the box is considered as not
           being ticked. The default value is 1.0, so that this feature is disabled.

       --grain granularity --arrondi rounding
           ask marks to be rounded to a multiple of granularity. If rounding is 'i', rounding is
           done from below (as with floor(3)). If rounding is 'n', rounding is done to the
           nearest multiple of granularity. If rounding is 's', rounding is done from above (as
           with ceil(3)). For example, with options "--grain 0.25 --arrondi s", mark 6.285 is
           rounded to 6.5.

       --notemin min
           with this option, all marks below min will be replaced by min.

       --notemax max
           gives the mark to associate to a sheet where all answers are correct. If not used,
           marks are not scaled.

       --plafond
           with this option, all marks above max will be replaced by max.

       --debug file.log
           gives a file to fill with debugging information.

       --postcorrect-student s --postcorrect-copy c
           requests port-correction from the completed answer sheet identified by student and
           copy numbers. In post-correction mode, correct answers are not extracted from the
           LaTeX source file, but taken from the answers given on this sheet.
