Hello people
   I had a problem in the postproc part of regcm4. I made a simulation including aerosols for the year 2000( idate0  = 2000010100,
 idate1  = 2000010100, idate2  = 2001010100,) and the simulation has successful completed. I have all the out put.(ATM,SRF,RAD,and CHE)
Next when I try to do the postproc part I encountered the following problem.
I get the sigma2pre and average for the 11 monthes and for the 12th month I get the following error message.
forrtl: severe (36): attempt to access non-existent record, unit 10, file /scratch/netk/RCM4WODust/output/ATM.20001201

I checked if the file exists or not and it does exist but I don't know why I don't get sigma2pre and average for the 12th month for all the outputs. Can anyone figure out why?
Thanks
