| + | ==== Adding Every File as it's Own Case ==== | ||
| + | .* | ||
| + | That's all you need. The '.' matches any character except for a new line, and the '*' says the preceeding character can be matched 0 or more times.\\ | ||
| + | In the screenshot below, you can see this search makes a new case for every WSI file in the directory. | ||
| + | |||
| + | {{ :pattern search 3.png?600 |}} | ||
| + | |||
| + | Here are some examples of how .* behaves in a regex pattern: | ||
| + | |||
| + | abc.*def: This pattern would match strings that start with "abc" and are followed by any sequence of characters, eventually ending with "def". For example, it would match "abc123def" or "abcxyzdef". | ||
| + | |||
| + | .*\d+.*: This pattern would match strings that contain one or more digits anywhere in the string. The .* before and after \d+ allows for any characters before and after the digit(s). | ||
| + | |||
| + | In the screenshot below you can see that '.*-' matches only files that have a '-' in their name | ||

| + | ==== Adding Similarly Named Files into Cases ==== | ||
| + | |||
| + | What about if you have file(s) named in a similar way? | ||
| + | |||
| + | We can use some simple commands to sort these into cases. | ||
| + | |||
| + | Here you can see that typing '.' matches all files starting with the same character into a Case. | ||
| + | |||
| + | {{ :pattern search 4.png?600 |}} | ||
| + | |||
| + | |||
| + | If you have files with different names, but each case shares the first 4 letters or numbers, you can type '....' to group them together. | ||
| + | |||
| + | Another way to search and group together files into Cases is using [].\\ | ||
| + | Any search terms you put within the [] will be searched for.\\ | ||
| + | In the example below, we use ^[\d\w]* to find the starting pattern of each filename until it is interrupted by a special character e.g. '(' or '.' | ||
| + | |||
| + | {{ :pattern search 6.png?600 |}} | ||
| + | |||
| + | You can also chain several of these blocks together, for example:\\ | ||
| + | ^[\d\w]+-[\d\w]+-[\d\w] would find all files with three strings of alphanumeric characters, each separated by a '-' | ||
| + | |||
| + | ==== Finding Many Files for a Single Case ==== | ||
| + | |||
| + | You can use pattern search like a regular search engine to find 'files' in your selected folder\\ | ||
