# Track reconstruction from database export
|
|
## Prerequisities
|
|
* System which runs CERN Root (Tested on MacOS High Sierra 10.13.4)
|
|
* CERN Root (Tested on 6.13/03)
|
|
|
|
## Build and run
|
|
* Clone this repository
|
|
|
|
```
|
|
git clone https://git.divaldo.hu/divaldo/DB_Track.git
|
|
```
|
|
* Create a working directory or use the Debug folder which already contains a data file
|
|
* If you decided to use another folder, then copy the data.txt to it
|
|
* You can use make -jN to use N number of CPU cores to build the app
|
|
|
|
```
|
|
cd DB_Track/Debug
|
|
cmake ../
|
|
make
|
|
```
|
|
* If complete, you can run it with the following command:
|
|
|
|
```
|
|
./DB_Track
|
|
```
|
|
* Use Ctrl + C to exit
|
|
|
|
## If you have newer data
|
|
* Export format is CSV
|
|
* Columns separated with space (" ")
|
|
* Columns enclosed with nothing
|
|
* Columns escaped with nothing
|
|
* The query order: ch_id, time_sec, time_ns, peak_amp
|
|
* Ascending by time_sec and time_ns
|
|
|
|
Use this query:
|
|
```
|
|
SELECT ch_id, time_sec, time_ns, peak_amp FROM adatok.fb55 ORDER BY time_sec ASC, time_ns ASC INTO OUTFILE '/tmp/fb55_exp.csv' FIELDS TERMINATED BY ' ' ENCLOSED BY '' LINES TERMINATED BY '\n';
|
|
