## Introduction
Signal Chain (SCh) is a radar data processing library developed using [Python](www.python.org) at JRO. SCh provides modules to read, write, process and plot data.
## Installation
Install system dependencies, download the latest stable release from [svn](http://jro-dev.igp.gob.pe/svn/jro_soft/schain/Releases/) e.g. schainpy-2.2.5.tar.gz. and install it as a normal python package.
```
$ sudo apt-get install python-pip python-dev gfortran libpng-dev freetype* libblas-dev liblapack-dev libatlas-base-dev python-qt4 python-tk libssl-dev libhdf5-dev
$ tar xvzf schainpy-2.2.5.tar.gz
$ cd schainpy-2.2.5
$ sudo pip install ./
```
**Its recommended to install schain in a virtual environment**
```
$ sudo pip install virtualenv
$ virtualenv /path/to/virtual --system-site-packages
$ source /path/to/virtual/bin/activate
(virtual) $ cd schainpy-2.2.5
(virtual) $ pip install ./
```
## First Script
Read Spectra data (.pdata) - remove dc - plot spectra & RTI
Import SCh and creating a project
```python
#!/usr/bin/python
from schainpy.controller import Project
controller = Project()
controller.setup(id = '100',
name='test',
description='Basic experiment')
```
Adding read unit and operations
```python
read_unit = controller.addReadUnit(datatype='Spectra',
path='/path/to/pdata/',
startDate='2014/01/31',
endDate='2014/03/31',
startTime='00:00:00',
endTime='23:59:59',
online=0,
walk=0)
proc_unit = controller.addProcUnit(datatype='Spectra',
inputId=read_unit.getId())
op = proc_unit.addOperation(name='selectChannels')
op.addParameter(name='channelList', value='0,1', format='intlist')
op = proc_unit.addOperation(name='selectHeights')
op.addParameter(name='minHei', value='80', format='float')
op.addParameter(name='maxHei', value='200', format='float')
op = proc_unit.addOperation(name='removeDC')
```
Plotting data & start project
```python
op = proc_unit.addOperation(name='SpectraPlot', optype='other')
op.addParameter(name='id', value='1', format='int')
op.addParameter(name='wintitle', value='Spectra', format='str')
op = procUnitConfObj1.addOperation(name='RTIPlot', optype='other')
op.addParameter(name='id', value='2', format='int')
op.addParameter(name='wintitle', value='RTI', format='str')
controller.start()
```
Full script
```python
#!/usr/bin/python
from schainpy.controller import Project
controller = Project()
controller.setup(id = '100',
name='test',
description='Basic experiment')
read_unit = controller.addReadUnit(datatype='Spectra',
path='/path/to/pdata/',
startDate='2014/01/31',
endDate='2014/03/31',
startTime='00:00:00',
endTime='23:59:59',
online=0,
walk=0)
proc_unit = controller.addProcUnit(datatype='Spectra',
inputId=read_unit.getId())
op = proc_unit.addOperation(name='selectChannels')
op.addParameter(name='channelList', value='0,1', format='intlist')
op = proc_unit.addOperation(name='selectHeights')
op.addParameter(name='minHei', value='80', format='float')
op.addParameter(name='maxHei', value='200', format='float')
op = proc_unit.addOperation(name='removeDC')
op = proc_unit.addOperation(name='SpectraPlot', optype='other')
op.addParameter(name='id', value='6', format='int')
op.addParameter(name='wintitle', value='Spectra', format='str')
op = procUnitConfObj1.addOperation(name='RTIPlot', optype='other')
op.addParameter(name='id', value='2', format='int')
op.addParameter(name='wintitle', value='RTI', format='str')
controller.start()
```
