Calling GMAS using MATLAB

Hi, All.

I try to call GAMS from MATLAB but facing this error:

Error using gams

Could not write data with gdxDataWriteMapStart

Error in UIMA_GAMS (line 51)

gams('UIMA_GAMS_Function.gms',vs,bs,ts,A,I,RD,cHT,cWT,cLD,Dv,Lv,Pv,Ph,Db,Lb,HT);

It will be really appreciated if you can help me.
