I can't run M1_GrpfEst_HCPR3

[ycanblue]

Hello.

I try to M1_GrpfEst_HCPR3's M13_GrpQPP_VxSm.m.
but error occurs.

M13_GrpQPP_VxSm (54th line)
load(p2bpr{is,i},'bpr');

I think I need to files like /All_Preproc_Data/GWCR_HCPR3/172433_1LR.mat etc.
So can you tell me how to get this files or convert from HCP files to .mat files
