 This is a repository of code shared by the research community. The repository is intended to be a central hub for sharing, refining, and reusing code used for analysis of the [MIMIC critical care database](https://mimic.physionet.org). To find out more about MIMIC, please see: https://mimic.physionet.org

 ## How to contribute
 
 Our team has worked hard to create and share the MIMIC dataset. We encourage you to share the code that you use for data processing and analysis. Sharing code helps to make studies reproducible and promotes collaborative research. To contribute, please:

 We encourage users to share concepts they have extracted by writing code which generates a materialized view. These materialized views can then be used by researchers around the world to speed up data extraction. For example, ventilation durations can be acquired by creating the ventdurations view in [etc/ventilation-durations.sql](https://github.com/MIT-LCP/mimic-code/blob/master/concepts/ventilation-durations.sql).

 The `IF NOT EXISTS` syntax was introduced in PostgreSQL 9.3. Make sure you have the latest PostgreSQL version. While one possible option is to modify the code here to be function under earlier versions, we highly recommend upgrading as most of the code written in this repository uses materialized views (which were introduced in PostgreSQL version 9.4).
+
+## NOTICE
+
+```sql
+NOTICE:  materialized view "XXXXXX" does not exist, skipping
+```
+
+This is normal. By default, the script attempts to delete tables before rebuilding them. If it cannot find the table to delete, it outputs a notice letting the user know.
+
+## Stuck on copy
+
+Many users report that the scripts get stuck at the following point:
+
+```
+COPY 58976
+COPY 34499
+COPY 7567
+```
+
+This is expected. The 4th table is CHARTEVENTS, and this table can take many hours to load. Give it time, and ensure that the computer does not automatically hibernate during this time.
+
+Also note that eventually, the 4th line will read `COPY 0`. This is expected, see https://github.com/MIT-LCP/mimic-code/issues/182
