dataframe containing splice event information, including chromosome, strand, and genomic location of regions of interest

column name in splice_data that contains the delta PSI value for the splice event. Default is None, which will not include this information in the output

Additional keyword arguments to pass to the find_ptms_in_many_regions function, which will be fed into the `filter_ptms

Given splice event quantification from SpliceSeq (such as what can be downloaded from TCGASpliceSeq), annotate with PTMs that are found in the differentially included regions.
Parameters
----------
psi_data: pandas.DataFrame
dataframe containing splice event quantification from SpliceSeq. Must contain the following columns: 'symbol', 'exons', 'splice_type'.
splicegraph: pandas.DataFrame
dataframe containing exon information from the splicegraph used during splice event quantification. Must contain the following columns: 'Symbol', 'Exon', 'Chr_Start', 'Chr_Stop'.
gene_col: str
column name in psi_data that contains the gene name. Default is 'symbol'.
dPSI_col: str
column name in psi_data that contains the delta PSI value for the splice event. Default is None, which will not include this information in the output.
sig_col: str
column name in psi_data that contains the significance value for the splice event. Default is None, which will not include this information in the output.
extra_cols: list
list of additional columns to include in the output dataframe. Default is None, which will not include any additional columns.
coordinate_type: str
indicates the coordinate system used for the start and end positions. Either hg38 or hg19. Default is 'hg19'.
separate_modification_types: bool
Indicate whether to store PTM sites with multiple modification types as multiple rows. For example, if a site at K100 was both an acetylation and methylation site, these will be separated into unique rows with the same site number but different modification types. Default is True.
identify_flanking_sequences: bool
Indicate whether to identify and return the flanking sequences for the splice events. Default is False.
flank_size: int
Size of the flanking sequence to extract from the splice event. Default is 5, which will extract 5 bases upstream and downstream of the splice event. Only relevant if identify_flanking_sequences is True.
PROCESSES: int
Number of processes to use for multiprocessing. Default is 1 (single processing).
**kwargs: additional keyword arguments
Additional keyword arguments to pass to the find_ptms_in_many_regions function, which will be fed into the `filter_ptms
()` function from the helper module. These will be used to filter ptms with lower evidence. For example, if you want to filter PTMs based on the number of MS observations, you can add 'min_MS_observations = 2' to the kwargs. This will filter out any PTMs that have less than 2 MS observations. See the `filter_ptms
()` function for more options.
