% [time] = convert_indices_to_time(indices, frame_rate)
%
% Converts the vector of frame indices to time. The time vector will start
% at zero.
%
% Arguments:
%           indices: vecor, the frame indices
%           framerate:, scalar, the framerate in Hz
%
% Returns:
%           time: vector, the time vector
