You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: xASL_quant_SliceTiming_ShortestTR.m
    path of file: ./repos/ExploreASL/Functions/Quantification
    
    the code of the file until where you have to start completion: function [x] = xASL_quant_SliceTiming_ShortestTR(x)
%xASL_quant_SliceTiming_ShortestTR Calculate SliceReadoutTime for shortest TR
%
% FORMAT: [x] = xASL_quant_SliceTiming_ShortestTR(x)

% INPUT:
%   x     - struct containing pipeline environment parameters (REQUIRED)
% OUTPUT:

% DESCRIPTION: When the TR is set to "shortestTR" in the ASL acquisition,
%              each ASL scan will have its unique TR. As this is shortest,
%              there won't be a delay between the readout of the last slice
%              and the end
