[1] Quick Guide

Executing the program with -h option will display a concise help page.

$>./h5pAttrib -h

usage: h5pAttrib [OPTIONS] file

OPTIONS
-h, --help Print help page
-n, --nstep Print number of steps
-A, --fileA Print file attributes
-a n, --stepA n Print step attributes & values for time step n
-d n, --dataset n Print data sets names & values for time step n
-H, --header Print shorter version without the values

Examples:

1) Show file attribute names & values of sample.h5part

h5pAttrib -A sample.h5part
OR
h5pAttrib --fileA sample.h5part

2) Show step attribute names for time step 5 of sample.h5part

h5pAttrib -a 5 -H sample.h5part
OR
h5pAttrib --stepA 5 -H sample.h5part

$> ./h5pToGNUplot -h

usage: h5pToGNUplot -t TIMESTEP -1 VARIABLE#1 -2 VARIABLE#2 -i INPUTFILE [OPTIONAL_FLAGS]

FLAGS
-h, --help Print help page
-1 par, --1var par (REQUIRED) Takes first variable parameter to "par"
-2 par, --2var par (REQUIRED) Takes second variable parameter to "par"
-i file, --input file (REQUIRED) Takes input file name to "file"
-t step, --timestep step (REQUIRED) Sets the timestep to "step" (Value -1 will result in dumping values of all timesteps.)
-o file, --output file (OPTIONAL) Takes output file name to "file" (without this flag, the program will print to stdout)
-n num, --number num (OPTIONAL) Sets number of output points to "num"
-s idx, --start idx (OPTIONAL) Sets the starting particle index to "idx"

Examples:

1) Create GNU plot file output.txt from sample.h5part by ploting x vs px for timestep 54

h5pToGNUplot -t 54 -1 x -2 px -i sample.h5part -o output.txt

2) Create GNU plot file output.txt from sample.h5part by ploting x vs px for timestep 54
using 1200 points from particle index 76

h5pToGNUplot -t 54 -1 x -2 px -i sample.h5part -o output.txt -s 76 -n 1200

[2] To see number of timesteps in a h5part file

Executing the program h5pAttrib with -n flag will display the number of timesteps in the file.

EXAMPLE>>

$> ./h5pAttrib -n sample.h5part

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Printing number of timesteps for: sample.h5part ...

There are total 252 number of timesteps.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

done

[3] To see file attributes in a h5part file

File attribute contains information about the file. (file description etc...) Executing the program h5pAttrib with -A flag will display the file attributes in the file.

EXAMPLE>>

$> ./h5pAttrib -A sample.h5part

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Printing file attributes for: sample.h5part ...

The number of file attributes for file sample.h5part is 0 ...
There are no file attributes.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

done

NOTE: -H option will omit the list of values of file attributes.

[4] To see step attributes in a h5part file

Step attribute contains information that belongs to a specific step. (step name, timestep number, etc...) Executing the program h5pAttrib with -a flag will display the step attributes in the file.
Note that the timestep index should follow -a flag.

EXAMPLE>>

$> ./h5pAttrib -a 2 sample.h5part

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Printing step attributes for: sample.h5part ...

The number of step attributes for timestep #2 is 10 ...

Attribute #0 = Step
There are 1 elements in the attribute
Attribute Type is H5T_NATIVE_INT64
Printing 1 element value(s):
COUNT[0]: 2

Attribute #1 = Spos
There are 1 elements in the attribute
Attribute Type is H5T_NATIVE_DOUBLE
Printing 1 element value(s):
COUNT[0]: 0.143580

Attribute #2 = structLen
There are 1 elements in the attribute
Attribute Type is H5T_NATIVE_DOUBLE
Printing 1 element value(s):
COUNT[0]: 2.393000

.
.
.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

done

NOTE: -H option will omit the list of values of step attributes.

[5] To see dataset in a h5part file

Executing the program h5pAttrib with -d flag will display the datasets information in the file. (dataset name, type, number of elements, etc...) Executing the program h5pAttrib with -d flag will display the datasets information in the file.
Note that the timestep index should follow -d flag.

EXAMPLE>>

$> ./h5pAttrib -d 2 -H sample.h5part

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Printing names of datasets for: sample.h5part ...

The number of datasets for timestep #2 is 7 ...

Dataset Name #0 = id
Dataset Type is H5T_NATIVE_INT64
Number of elements: 67587

Dataset Name #1 = px
Dataset Type is H5T_NATIVE_DOUBLE
Number of elements: 67587

Dataset Name #2 = py
Dataset Type is H5T_NATIVE_DOUBLE
Number of elements: 67587

Dataset Name #3 = pz
Dataset Type is H5T_NATIVE_DOUBLE
Number of elements: 67587

Dataset Name #4 = x
Dataset Type is H5T_NATIVE_DOUBLE
Number of elements: 67587

Dataset Name #5 = y
Dataset Type is H5T_NATIVE_DOUBLE
Number of elements: 67587

Dataset Name #6 = z
Dataset Type is H5T_NATIVE_DOUBLE
Number of elements: 67587

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

done

NOTE: -H option will omit the list of values of datasets.

[6] Providing more than one flag at once

When more than one flags are provided, one result after another will be displayed.

EXAMPLE>>

$> ./h5pAttrib -H -a 1 -d 1 sample.h5part

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Printing step attributes for: sample.h5part ...

The number of step attributes for timestep #1 is 10 ...

Attribute #0 = Step
Attribute #1 = Spos
Attribute #2 = structLen
Attribute #3 = org
Attribute #4 = maxX
Attribute #5 = minX
Attribute #6 = maxP
Attribute #7 = minP
Attribute #8 = centroid
Attribute #9 = nloc
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Printing names of datasets for: sample.h5part ...

The number of datasets for timestep #1 is 7 ...

Dataset Name #0 = id
Dataset Type is H5T_NATIVE_INT64
