Cannot allocate memory

Hi,

When I use my viral proteins and GOV2 proteins to run vcontact2. It is really slow and I meet the following error.

ESC[1;42mINFOESC[1;0m:vcontact2: Building the cluster and profiles (this may take some time...)
If it fails, try re-running using --blast-fp flag and specifiying merged.self-diamond.tab (or merged.self-blastp.tab)
ESC[1;42mINFOESC[1;0m:vcontact2: Saving intermediate files...
ESC[1;42mINFOESC[1;0m:vcontact2: Read 5323784 entries (dropped 88261 singletons) from Mariana_Prokaryotic_vContact/vConTACT_profiles.csv

OSError: [Errno 12] Cannot allocate memory

I successfully got these files (vConTACT_proteins.csv, vConTACT_contigs.csv,vConTACT_pcs.csv, vConTACT_profiles.csv, merged_df.csv)

After reading your wiki, it seems I can rerun from those files. How should I do?

Thanks
