Also beware, since one of the dimensions is white matter voxels, the dconn from -convert-matrix4-to-matrix2 will be larger than a standard 91k dconn (78GB based on the information you posted, versus ~30GB for a 91k dconn).
Surface-to-surface tractography would normally be done with a different output format. You may be able to approximate it with a hack by generating a volume ROI just inside the white matter surface, but that will be somewhat angle-dependent in its response, so I wouldn't trust it much.
