Fix logic that determines if nifti file is compressed

[faridyagubbayli]

Context

The logic which decides if remote nifti file is compressed or not has a flaw. It checks the end of the URL string for .gz extension. When url includes parameters/headers, .gz extension appears in the middle of the string.

For example, current logic will work for a URL like: https://<some_address>/<filename>.nii.gz but fail for a url like https://<some_address>/<filename>.nii.gz?<some_param>=<some_value>.

Changes & Results

This PR updates the logic to check for inclusion of the .gz extension anywhere in the string.

Testing

Tested in a limited local environment and works as expected.

but then how are you cleaning the url for the fetch?

[faridyagubbayli]

I don't need to clean the url. In my case, I use a signed URL and additional parameters are needed for authentication.

[daker]

Maybe use URL api instead

const url = "https://toto.blob.core.windows.net/mycontainer/sample.nii.gz?sv=2019-10-10&ss=bfqt&srt=sco&sp=rwdlacupx&se=2020-07-17T10:09:48Z&st=2020-07-17T02:09:48Z&spr=https&sig=xxxxxxxxx";
const _url = new URL(url);
const isCompressed = _url.pathname.endsWith('.gz');
console.log(isCompressed);


const url = "https://myserver.com/sample.nii.gz";
const _url = new URL(url);
const isCompressed = _url.pathname.endsWith('.gz');
console.log(isCompressed);
