could transrate be used to merge assembly from trinity

[pandafish123]

Hi,
I am using Trinity to assemble transcriptomes from 21 samples. Since I cannot assemble the reads from all sample into a single Trinity run which consumes LOTS of RAM, I am assembling each data set independently.
I want to merge all assemblies (21 trinity.fasta files) into a single, unified assembly. I see that transrate has the function that merge-assemblies= ( Merge best contigs from multiple assemblies into file).
So i was wondering whether Transate could be used to merge 21 assemblies into one assembly for DE analysis and so on.

Hope for your advice.

Thanks a lot.

Repick.
