abagen.io.read_probes

abagen.io.read_probes(fname, copy=False)

Loads Probes.csv file found at fname

Probe files contain metadata on all genetic probes used in the AHBA data. These files should be the same for every donor.

This information can be used to e.g., query expression data for certain genes, collapse data across probes from the same gene, etc.

Parameters

• fname (str) – Path to Probes.csv file

• copy (bool, optional) – Whether to return a copy if fname is a pre-loaded pandas.Dataframe. Default: False

Returns

probes – Dataframe containing information for P genetic probes. The row index is the unique probe ID assigned during processing, which can be used to match metadata to information obtained with read_microarray() and read_pacall(). Columns include ‘probe_name’, ‘gene_id’, ‘gene_symbol’, ‘gene_name’, ‘entrez_id’, and ‘chromosome’.

Return type

(P, 6) pandas.DataFrame
