Hello Autumn,
As per my understanding you want to find specific value in h5 file.
Please note that you can use the `h5info` function in MATLAB to recursively search for the 'Record Interval' attribute or dataset within the h5 file. Here's an example of how you can achieve this:
function location = findRecordInterval(filePath)
file = h5info(filePath);
location = recursiveSearch(file, '');
end
function location = recursiveSearch(group, location)
% Check if the 'Record Interval' attribute exists in the current group
attributes = {group.Attributes.Name};
if ismember('Record Interval', attributes)
location = [location '.Attributes'];
return;
end
% Check if the 'Record Interval' dataset exists in the current group
datasets = {group.Datasets.Name};
if ismember('Record Interval', datasets)
location = [location '.Datasets'];
return;
end
% Recursively search subgroups
for i = 1:length(group.Groups)
subgroup = group.Groups(i);
location = recursiveSearch(subgroup, [location '.Groups(' num2str(i) ')']);
if ~isempty(location)
return;
end
end
% If 'Record Interval' is not found, return an empty location
location = '';
end
To use this code, you can call the `findRecordInterval` function with the path to your h5 file as an input. It will return the location of the 'Record Interval' attribute or dataset within the file. The location will be a string indicating the path to the attribute or dataset, such as `.Attributes` or `.Datasets`.
Note that this code assumes that the 'Record Interval' attribute or dataset is unique within each file. If there are multiple occurrences, it will return the location of the first occurrence found. You can modify the code if you need to handle multiple occurrences differently.
For more information regarding h5info you can refer following article:
I hope it helps.
