combine metagenomic assemblies using cat?

I am working on metagenomic project where I have replicates for each sampling location. I originally wanted to combine the forward and reverse .fastq files and create one assembly for each site, but the problem I am having is that the combined files are too large for assembly (I get unresolvable errors on my universities HPC related to temporary memory)

Is there any reason I cant assemble each replicate on its own and then just concatenate them into one larger assembly?

If there are better work around ideas here they are appreciated.

assembly

Hey,

some assemblers are pretty demanding in terms of memory. I would try megahit. Alternativelly, ask for more RAM.

Is there any reason I cant assemble each replicate on its own and then just concatenate them into one larger assembly?

This is perfectly fine however, you might loose low coverage genomes/contigs.
