I am stuck with a problem that sst and icbc scripts of RegCM4.6.0 give following error for MPI-ESM-MR RCP26 forcing file:

"forrtl: severe (64): input conversion error, unit -5, file Internal Formatted Read"

Note that the model produces ICBC files and runs without any problem for MPI-ESM-MR historical forcing files (for RCP85 files too).

I have noticed that MPI-ESM-MR RCP26 was produced by the command of "cdo -t echam6 -f nc4c -z zip" ("cdo -t echam6 -f nc4 -z zip" for other forcing files) and apparently has somehow different format, therefore, icbc part fails to work. I have tried several options including the changing file format, attributes etc. with cdo and nco, however, the same problem still exists.
