Problem in the database when using the append function.

[ggilestro]

Commit 7853b44 created an issue.
When data are appended to an existing database, the variable t restarts from 0 and that creates a wrong series in the column.

A workaround for existing databases is to open the db file and issue the following SQL:

UPDATE ROI_1 SET t = t + ( SELECT MAX(t) from ROI_1 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_1));
UPDATE ROI_2 SET t = t + ( SELECT MAX(t) from ROI_2 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_2)); 
UPDATE ROI_3 SET t = t + ( SELECT MAX(t) from ROI_3 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_3)); 
UPDATE ROI_4 SET t = t + ( SELECT MAX(t) from ROI_4 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_4)); 
UPDATE ROI_5 SET t = t + ( SELECT MAX(t) from ROI_5 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_5)); 
UPDATE ROI_6 SET t = t + ( SELECT MAX(t) from ROI_6 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_6)); 
UPDATE ROI_7 SET t = t + ( SELECT MAX(t) from ROI_7 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_7)); 
UPDATE ROI_8 SET t = t + ( SELECT MAX(t) from ROI_8 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_8)); 
UPDATE ROI_9 SET t = t + ( SELECT MAX(t) from ROI_9 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_9)); 
UPDATE ROI_10 SET t = t + ( SELECT MAX(t) from ROI_10 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_10)); 
UPDATE ROI_11 SET t = t + ( SELECT MAX(t) from ROI_11 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_11)); 
UPDATE ROI_12 SET t = t + ( SELECT MAX(t) from ROI_12 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_12)); 
UPDATE ROI_13 SET t = t + ( SELECT MAX(t) from ROI_13 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_13)); 
UPDATE ROI_14 SET t = t + ( SELECT MAX(t) from ROI_14 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_14)); 
UPDATE ROI_15 SET t = t + ( SELECT MAX(t) from ROI_15 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_15)); 
UPDATE ROI_16 SET t = t + ( SELECT MAX(t) from ROI_16 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_16)); 
UPDATE ROI_17 SET t = t + ( SELECT MAX(t) from ROI_17 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_17)); 
UPDATE ROI_18 SET t = t + ( SELECT MAX(t) from ROI_18 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_18)); 
UPDATE ROI_19 SET t = t + ( SELECT MAX(t) from ROI_19 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_19)); 
UPDATE ROI_20 SET t = t + ( SELECT MAX(t) from ROI_20 ) WHERE id > (SELECT id from (SELECT id, MAX(t) from ROI_20)); 

However, this needs to be fixed in the code by inheriting and maintaining the same t0 . We also need to add a new metadata table with a different name (such as metadata_1) rather than simply overwrite the content of the metadata table.

The script above will not work if the t value is largest at the end of the experiment, for instance in cases like the one below.

What we need to identify is the first peak, which is the only point where id.t < id.t+1 with the following script:

SELECT t FROM (
	SELECT
		g1.id,
		g1.t,
		(g2.t - g1.t) as delta
	FROM
		ROI_1 g1
			INNER JOIN
		ROI_1 g2 on g2.id = g1.id + 1
	WHERE
		delta < 0
)

Which in one row becomes

UPDATE ROI_1 SET t = t + (SELECT FIT from (SELECT g1.id as FID, g1.t as FIT, (g2.t - g1.t) as delta FROM ROI_1 g1 INNER JOIN ROI_1 g2 on g2.id = g1.id + 1 WHERE delta < 0)) WHERE id > (SELECT FID FROM (SELECT g1.id as FID, g1.t as FIT, (g2.t - g1.t) as delta FROM ROI_1 g1 INNER JOIN ROI_1 g2 on g2.id = g1.id + 1 WHERE delta < 0));

And this solves the issue

So the full sequence to use is the following:

UPDATE ROI_1 SET t = t + (SELECT FIT from (SELECT g1.id as FID, g1.t as FIT, (g2.t - g1.t) as delta FROM ROI_1 g1 INNER JOIN ROI_1 g2 on g2.id = g1.id + 1 WHERE delta < 0)) WHERE id > (SELECT FID FROM (SELECT g1.id as FID, g1.t as FIT, (g2.t - g1.t) as delta FROM ROI_1 g1 INNER JOIN ROI_1 g2 on g2.id = g1.id + 1 WHERE delta < 0));
