hc3 - spike_count table missing

Posted by Scott Cole at April 28. 2017

I'm trying to find recordings in hc3 with high spike counts, as shown in some of the sample SQLite queries. However, I am getting the error: `Error: no such table: spike_count`. And when I check, I see that the spike_count table does not exist in hc3-tables.db (as the documentation suggests it does). I can access all of the rest of the tables (cell, epos, file, and session).

Am I somehow in the wrong file? Where can I find the spike_count table?

Thank you for your time!

It seems to be working for me. Below is a dialog with a fresh download of crcns-hc3-metadata-tables.zip;

$ ls

crcns-hc3-metadata-tables crcns-hc3-metadata-tables.zip

$ cd crcns-hc3-metadata-tables

$ ls

hc3-cell.csv hc3-file.csv hc3-session_a.csv hc3-tables.db hc3-tables.xlsx

$ ~/bin/sqlite3 hc3-tables.db

CREATE TABLE IF NOT EXISTS "spike_count" (

All the files are there now. Thanks!

Strange. When I downloaded crcns-hc3-metadata-tables.zip on April 28, from the link on http://crcns.org/data-sets/hc/hc-3/about-hc-3, there were no tables for 'hc3-session_a' or 'hc3-spike count'. Anyway. No longer an issue.
