CRITICAL ERROR: Decomoposition file: contains less than 1064 cells

I am trying to get a regional forecast running. Have had no problems up to now, but this is a bigger region, namely Texas. As the error notes: the **" file contains less than 1064 cells. First, not sure where the 1064 cell criteria would be set for this case. Secondly, how can I circumvent this issue? The command I am using to build this decomposition file is: "gpmetis -minconn -contig -niter=200 6". Do I simply need to alter this command slightly to get 1064 cells? Any clues are welcome. TIA.
Thanks for following up to let us know you've resolved the issue! To answer a question from your original post, the number 1064 should be the number of cells in your regional domain. Essentially, the file should contain 1064 lines, each with an integer in the range [0,5] assigning each cell to one of six partitions (corresponding to the ".part.6" suffix).
