In this step you have to transfer the results from the res.dat file (or its copy) back to NMRPipe format, filling in the missing FIDs by calculated values. The input files are the output from Step 4 (same as input for Step 5) and res.dat file for MPI version or the region list file for the multiregion version. The output is a new reconstructed NMRPipe file with the directly detected dimension Fourier transformed. Press the RECONSTRUCT button and check for progress output and any error messages in the console window. Move to the last step.
