W-SLDA Toolkit provide various tools that may support computation and data analysis process.
|
|
|
|
In order to create them enter [tools](https://gitlab.fizyka.pw.edu.pl/gabrielw/wslda/-/tree/public/tools) folder and edit (if necessary) header of [Makefile](https://gitlab.fizyka.pw.edu.pl/gabrielw/wslda/-/blob/public/tools/Makefile). Next execute
|
|
|
|
```bash
|
|
|
|
make
|
|
|
|
```
|
|
|
|
Executables will be written to `wslda/tools/bin` folder.

## wdata-cut
|
|
|
|
*Purpose*: extracts subset from existing wdata set.
|
|
|
|
|
|
|
|
In many cases for testing purposes it is sufficient to have only sample of data (for example to download it locally and test a code). You can use `wdata-cut` tool exatract a data sample. Syntax is following:
|
|
|
|
```bash
|
|
|
|
Usage: ./wdata-cut file.wtxt outprefix start stop
|
|
|
|
file.wtxt - metadata file
|
|
|
|
outprefix - for new files, metadata file will be written to outprefix.wtxt
|
|
|
|
[start,stop) - range for subtructing cycles
|
|
|
|
```
|
|
|
|
For example to extract the first cycle only:
|
|
|
|
```bash
|
|
|
|
[gabrielw@dell tools]$ ./wdata-cut ../lib-wdata/test.wtxt ./sample 0 1
|
|
|
|
WDATA SUBSET EXTRACTOR
|
|
|
|
WORKING DIR: `../lib-wdata` --> `.`
|
|
|
|
SUBTRUCTION RANGE: [0,1)
|
|
|
|
READING FILE: `../lib-wdata/test.wtxt`
|
|
|
|
WRITING NEW METADAFILE: `./sample.wtxt`
|
|
|
|
DONE.
|
|
|
|
```
|
|
|
|
## wdata-sample
|
|
|
|
|
|
|
|
*Purpose*: creates new data set, where only every `stride` measurment is present.
|
|
|
|
|
|
|
|
This tool is very similar to `wdata-cut` tool with change that it strides the data set. Syntax is following:
|
|
|
|
```bash
|
|
|
|
Usage: wdata-sample file.wtxt outprefix stride
|
|
|
|
file.wtxt - metadata file
|
|
|
|
outprefix - for new files, metadata file will be written to outprefix.wtxt
|
|
|
|
stride - take only every stride measurment
|
|
|
|
```
|
|
|
|
## dpca2wdata
|
|
|
|
*Purpose*: creates wtxt metadata file for existing dpca files.
|
|
|
|
|
|
|
|
Syntax:
|
|
|
|
```bash
|
|
|
|
[gabrielw@dell tools]$ ./dpca2wdata
|
|
|
|
Usage: ./dpca2wdata prefix
|
|
|
|
prefix - prefix of dpca files
|
|
|
|
```
|
|
|
|
Example of usage:
|
|
|
|
```bash
|
|
|
|
[gabrielw@node2066 CALC-UFG]$ ls ufg1V0.6*.dpca
|
|
|
|
ufg1V0.6_current_a.dpca ufg1V0.6_current_b.dpca ufg1V0.6_delta.dpca ufg1V0.6_density_a.dpca ufg1V0.6_density_b.dpca
|
|
|
|
[gabrielw@node2066 CALC-UFG]$ dpca2wdata ufg1V0.6

## wdata2checkpoint
|
|
|
|
*Purpose*: Converts W-DATA results into checkpoint file than can be used as starting point for self-consistent process.
|
|
|
|
```bash
|
|
|
|
Usage: ./wdata2checkpoint file.wtxt outprefix
|
|
|
|
or
|
|
|
|
Usage: ./wdata2checkpoint file.wtxt outprefix cycleid
|
|
|
|
file.wtxt - metadata file
|
|
|
|
outprefix - checkpoint will be written to outprefix
|
|
|
|
cycleid - use given cycleid to create checkpoint file, default: cycleid=last cycle
