I admit I haven't searched for nor read information on h5stat. So, if

someone wants to tell me to rtfm, thats fine. Just tell me what to read.

Otherwise, I have some questions interpreting this output from h5stat...

Dataset dimension information:

Max. rank of datasets: 2

Dataset ranks:

# of dataset with rank 1: 188

# of dataset with rank 2: 18

I assume 'rank' is the number of dimensions. right?

1-D Dataset information:

Max. dimension size of 1-D datasets: 9

Ok, this totaly throwse me. What does 'dimension size' mean? It cannot

possibly mean the maximum size of a dimension in 1D datasets as the file

contains 1D datasets of size 1 all the way up to several thousand.

Small 1-D datasets:

# of dataset dimensions of size 1: 45

# of dataset dimensions of size 4: 3

# of dataset dimensions of size 6: 3

# of dataset dimensions of size 8: 3

# of dataset dimensions of size 9: 1

Ditto here. I just don't understand what the above lines are telling me?

How is 'small' defined? Is that controlled by any command-line switch?

Total small datasets: 55

1-D Dataset dimension bins:

# of datasets of size 1 - 9: 55

# of datasets of size 10 - 99: 117

# of datasets of size 100 - 999: 10

# of datasets of size 1000 - 9999: 4

# of datasets of size 10000 - 99999: 1

# of datasets of size 1000000 - 9999999: 1

Total # of datasets: 188

This is great. But, I have 2D datasets also. Why don't I see similar

output for 2D datasets?

Hi Mark,

I admit I haven't searched for nor read information on h5stat. So, if

someone wants to tell me to rtfm, thats fine. Just tell me what to read.

Dataset dimension information:

Yes.

1-D Dataset information:

Max. dimension size of 1-D datasets: 9

possibly mean the maximum size of a dimension in 1D datasets as the file

contains 1D datasets of size 1 all the way up to several thousand.

Hmm, it does mean that, so the h5stat tool may have a bug. Are you working with the latest (1.8.4) release?

Small 1-D datasets:

# of dataset dimensions of size 1: 45

# of dataset dimensions of size 4: 3

# of dataset dimensions of size 6: 3

# of dataset dimensions of size 8: 3

# of dataset dimensions of size 9: 1

Ditto here. I just don't understand what the above lines are telling me?

"small" is <10. It's not a user-tunable request (but I'll file an enhancement request for you

Total small datasets: 55

1-D Dataset dimension bins:

# of datasets of size 1 - 9: 55

# of datasets of size 10 - 99: 117

# of datasets of size 100 - 999: 10

# of datasets of size 1000 - 9999: 4

# of datasets of size 10000 - 99999: 1

# of datasets of size 1000000 - 9999999: 1

Total # of datasets: 188

This is great. But, I have 2D datasets also. Why don't I see similar

output for 2D datasets?

Well, it seemed like it would be much more complex for 2D datasets, since there would be n^2 combinations possible, and n^3 combinations for 3D datasets, etc. I'll file another enhancement request to revisit this idea and see if we can come up with good ways to present the information for 2+ dimension datasets.
