genBlastA output file .gblast error

Hey guys,

Recently, I was trying to identify homologous genes in different genomes using genBlastG, however when I run it with default parameters, it generates a huge (~4G) empty output file (.gblast extension with other string attached, i.e., XX.gblast_1.1c_2.3_s1_0_16_1). Other intermediates file seems right, such as .blast and .report files.

I tried so many times with various modifications but the problem still exists. Does anyone know about this problem?

Many Thanks!
