System requirements

CLC Microbial Genomics Module 23.0.3 is for use with CLC Genomics Workbench version 23 or newer. The system requirements for CLC Genomics Workbench are provided at http://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=System_requirements.html.

The system requirements for CLC Microbial Genomics Module are the same as those for CLC Genomics Workbench, except for the following:

Special requirements for the MLST Scheme tools

The system requirements for the MLST Scheme tools depend on the size of the MLST schemes (both the number of alleles and the number of sequence types). A laptop with 16GB of memory is normally sufficient for 7-gene schemes or cgMLST schemes based on a moderate number of isolates. Downloading and constructing or typing with larger schemes may require more memory, and in general we recommend at least 64GB of memory when working with cg/wgMLST schemes based on more than 100 isolates.

Special requirements for OTU Clustering

The memory requirements of Reference based OTU clustering are dependent on the size of the reference database used; more and longer sequences require more run time and memory. Newer version of common choices (e.g. the full SILVA SSU database) are likely to be too large for a 16 GB machine. Instead we recommend using clustered databases (e.g. the SILVA SSU 99% database) and/or otherwise filtering and subsetting the database, to minimize its size.

Special requirements for Taxonomic Profiling

The performance of the Taxonomic Profiling tool depends on the reference database used - the more complete a database, the better the taxonomic profiling. However, running Taxonomic Profiling with a given database size will require at least the same amount of memory. For example, a 14 GB database requires at least 16 GB of RAM, and a 56 GB database requires a minimum of 64 GB RAM. When creating your reference database with the Download Custom Microbial Reference Database tool, you will get a warning about the memory requirements needed for running the Taxonomic Profiling tool with this database.

Special requirements for De Novo Assemble Metagenome

At least 16 GB RAM is recommended for running De Novo Assemble Metagenome.
