You should be saving all of the MRFs.

Here is the information that described the change that was put in place when Version 7.6 was released Release Notes http://www.unidata.ucar.edu/packages/mcidas/mcx/release_notes.html Aviation Run of the MRF Model Beginning with this upgrade, grids from the Aviation run of the Medium Range Forecast (MRF) model will be labeled AVN. In previous versions, these grids were labeled MRF. The reasons for the label change are listed below. The Aviation and MRF runs use different data. The MRF run is started after the Aviation run and uses additional data in its initialization grids. Giving different labels to the grids provides increased flexibility in grid filing methods. Most grid users differentiate between the Aviation run and the MRF run of the MRF model. Required Action: If you are upgrading from a previous version of McIDAS-XCD, complete the steps below to configure the GRIB decoder to file the AVN grids in their own grid file range. 1.As the user mcidas start a McIDAS-X session. Then, in the McIDAS-X Text and Command Window stop the GRIB decoder. Type: DECINFO SET DMGRID INACTIVE 2.From the Unix shell, change to the ~mcidas/data directory Type: cd ~mcidas/data 3.Edit the file RTMODELS.CFG and add a line similar to the one listed below, which configures the GRIB decoder to file AVN grids in the grid file range 5401 through 5480. If you want to file the grids in a range other than the default range, then change 5401 to the beginning grid file number of your choice. Note that the filing format specified in the example below will consume 80 grid files. After adding the appropriate line to RTMODELS.CFG, write and quit the file. AVN= 3 5401 120000 240000 720000 4.Restart the GRIB decoder. Type: DECINFO SET DMGRID ACTIVE Complete the steps below to add a new ADDE real-time dataset for the AVN grid files configured in steps 1 through 4 above. 1.In the existing McIDAS-X session, and run a command similar to the one listed below. If you chose a different starting grid file number in step 3 above, adjust the numeric range in the command below accordingly. Type: DSSERVE ADD RTGRIDS/AVN GRID 5401 5480 RT=YES "Real-Time AVN Grids 2.Exit the McIDAS-X session and logoff. >If not, what is the >difference, and how did we lose the MRF? Your listing of MRF files is not what it should be.

This is what I don't understand. I will try to logon to your machine to see what may be going on sometime this weekend. Tom
