For xRollDir test, created two sets of pairs of variables to hold data for a positive and minus direction: xRollDirPos: FxAppPos,FzAppPos and the minus direction. Corrected snapVerification, loadFCData, updateHistData, failureCharacterization... also changed zeroFill padding to place values = -99 and included processing of number of elements for MCs in failureCharac.
