I am new user of wrf-cmaq. The wrf and cmaq both seperately runs ok, but when I coupled the wrf and cmaq, an error happened. I am using the wrf3.8 and cmaq5.2 version, and downloaded the “WRF3.8\_CMAQ5.2\_TwoWay\_Model.tar.gz”.  
I installed the wrf3.8-cmaq5.2 following the instructions, but when I run command “two-way/assemble”, the error of “ls: No match” comes and then nothing happened.

Please help me to figure it out if you know this.  
Many thanks!
