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.
