When using

`nonpoint/Annual_np_oilgas_12US1_2017gb_17j_TestCase.csh`

We found the following system error:

```auto
smoke4.7/scripts/run/source set_months_v4.csh -m 7 0
source: Too many arguments.

```

Which stopped the execution. After too many search, we found that:

- `csh`: does not accept to ‘source’ a file with arguments: `suorce [file] [arguments]`
- `tcsh`: (enhanced retrocompatible`csh`) does accept arguments when sourcing  
We found that in most linux environments, users tend to link `tcsh` as `csh`

At the same time, we need to modify some scripts:

- At line #1 of `smoke4.7/scripts/log_analyzer/log_analyzer.py`, `smoke4.7/scripts/run/path_parser.py`, `smoke4.7/scripts/annual_report/annual_report_v2.py` we needed to update python call as

```auto
#!/usr/bin/env python3

```

- On line # 30 of `smoke4.7/scripts/run/set_months_v4.csh`, erroneous syntax on providing arguments: it is being provided as `$#` (`sh/bash`) and to be 100% `csh` should be `$#argv` [web](https://www.unix.com/shell-programming-and-scripting/42713-read-number-arguments-c-shell.html):

```auto
if ( $#argv == 3 ) then

```

Can you clarify where the nonpoint script came from? Was it part of the EPA installation package or part of the EPA 2017 platform posted here:
