omicverse.io.read_csv(filepath_or_buffer=None, *, sep=None, on_duplicate='warn', **kwargs)[source]#

Read a CSV / TSV file via pandas.read_csv with a mandatory duplicate-column scan on the raw header.

Parameters:

  • filepath_or_buffer (default: None) – Same as pandas.read_csv. Accepts a path-like, a URL, or a file-like object. The duplicate scan only runs when the input is a real on-disk file path.

  • sep (str | None (default: None)) – Delimiter. Inferred from extension when None (.csv → ,, .tsv/.txt/.tab → \t).

  • on_duplicate (str (default: 'warn')) –

    Action when duplicate column labels are found in the raw header. One of:

    • "warn" (default) — print a remediation-pointing message to stdout and continue with pandas’s auto-rename.

    • "raise" — raise ValueError with the same message.

    • "ignore" — silent passthrough; identical to pandas.read_csv.

  • **kwargs – Any other keyword argument accepted by pandas.read_csv (for example index_col, dtype, usecols, comment).

Return type:

pandas.DataFrame
