 ## Dumping data from a MySQL database
 
-To dump data into a ttl file, first make sure that you are in the guix environment in the "dump-genenetwork-database" repository
-
-=> https://github.com/genenetwork/dump-genenetwork-database/ Dump Genenetwork Database
-
-Next, drop into a development environment with:
-
-```
-$ guix shell -m manifest.scm
-```
-
-Build the sources:
-
-```
-$ make
-```

-Describe the database connection parameters in a file *conn.scm* file as shown below. Take care to replace the placeholders within angle brackets with the appropriate values.

- (sparql-scheme . http)

-Then, to dump the database to \~/data/dump, run:
-
-```
-$ ./pre-inst-env ./dump.scm conn.scm ~/data/dump
-```
-
-Make sure there is enough free space! It\'s best to dump the database on penguin2 where disk space and bandwidth are not significant constraints.
+To dump data into a ttl file, first make sure that you are in the guix environment in the "dump-genenetwork-database" repository
 
-Then, validate the dumped RDF using `rapper` and load it into virtuoso. This will load the dumped RDF into the `http://genenetwork.org` graph, and will delete all pre-existing data in that graph.
