440 Convert a BAM file`to a fragment file, `using pp.make_fragment_file`
441 ====================================================================
442
443 Convert a BAM file to a fragment file.
444
445 Convert a BAM file to a fragment file by performing the following steps:
446
447 - Filtering: remove reads that are unmapped, not primary alignment, mapq < 30, fails platform/vendor quality checks, or optical duplicate. For paired-end sequencing, it also removes reads that are not properly aligned.
448
449 - Deduplicate: Sort the reads by cell barcodes and remove duplicated reads for each unique cell barcode.
450
451 - Output: Convert BAM records to fragments (if paired-end) or single-end reads.
452
453 The bam file needn’t be sorted or filtered.

458 Import data fragment file` and compute basic QC metrics, using `pp.import_data`
459 ===============================================================================
460
461 Import data fragment files and compute basic QC metrics.
462
463 A fragment refers to the sequence data originating from a distinct location in the genome. In single-ended sequencing, one read equates to a fragment. However, in paired-ended sequencing, a fragment is defined by a pair of reads. This function is designed to handle, store, and process input files with fragment data, further yielding a range of basic Quality Control (QC) metrics. These metrics include the total number of unique fragments, duplication rates, and the percentage of mitochondrial DNA detected.
464
465 How fragments are stored is dependent on the sequencing approach utilized. For single-ended sequencing, fragments are found in `.obsm['fragment_single']`. In contrast, for paired-ended sequencing, they are located in `.obsm['fragment_paired']`.

494 Filter cell outliers based on counts and numbers of genes expressed, using `pp.filter_cells`
495 ============================================================================================
496
497 Filter cell outliers based on counts and numbers of genes expressed. For instance, only keep cells with at least `min_counts` counts or `min_ts`` TSS enrichment scores. This is to filter measurement outliers, i.e. “unreliable” observations.

510 Compute probability of being a doublet using the scrublet algorithm, using `pp.scrublet`
511 ========================================================================================
512
513 Compute probability of being a doublet using the scrublet algorithm.
514
515 This function identifies doublets by generating simulated doublets using randomly pairing chromatin accessibility profiles of individual cells. The simulated doublets are then embedded alongside the original cells using the spectral embedding algorithm in this package. A k-nearest-neighbor classifier is trained to distinguish between the simulated doublets and the authentic cells. This trained classifier produces a “doublet score” for each cell. The doublet scores are then converted into probabilities using a Gaussian mixture model.

524
525 The user can choose to remove doublets by either the doublet probability or the doublet score. `scrublet` must be ran first in order to use this function.

560
561 Compute the fragment size distribution of the dataset.
562
563 This function computes the fragment size distribution of the dataset. Note that it does not operate at the single-cell level. The result is stored in a vector where each element represents the number of fragments and the index represents the fragment length. The first posision of the vector is reserved for fragments with size larger than the `max_recorded_size` parameter. `import_data` must be ran first in order to use this function.
