SomaScan/Olink example from PRIDE Affinity Archive

[ypriverol]

This pull request adds a new sample and data relationship format (SDRF) file for the PAD000001 dataset, detailing metadata for 20 blood plasma samples analyzed using Olink Explore 1536 technology.

Sample metadata and annotations:

• Added examples/PAD000001/PAD000001.sdrf.tsv containing metadata for 20 human blood plasma samples, including organism, disease status, age, sex, and individual identifiers.
• Included detailed assay and platform information for each sample, specifying the use of Olink Explore 1536 and NPX normalization.
• Provided explicit annotations for technical and biological replicates, sample matrix, and disease classification (prediabetes or normal).

Data provenance and versioning:

• Added references to associated data files and versioning information for SDRF and template specifications.

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

@magnuspalmblad this is a good example of the PRIDE affinity Archive if you have comments would be great.

Blood plasma instead of blood
remove the extra characteristics[precondition] column
sampling time check if its 7 day or 7D
Something more generic for characteristics [smoking status]
remove characteistics [sample matrix], comment [sdrf version], sdrf template x2, panel name, somascan menu, somascan platform
modify comment [platform] to be SomaScan 7K
 remove plate position, sample collection date, diltuion, normalizaion method, quantification unit,
the column characteristics [disease] is wrong. The values should be normal/sard-cov-2, instead of just mentioning the disease studied in the article. The correct data is in the column factor value [disease], although the values should be normal (instead of negative).
Remove who peak severty, who severity at sampling, fatal disease
