Inline comments:
In `@algorithms/MDLMDec/apply_standalone_model.py`:
- Around line 14-19: Update the cleanup logic around the length calculation to
first track which rows contain an EOS or NT token, and apply the EOS/NT
replacements only to those rows. Leave sequences with no terminal token
unchanged while preserving the existing cleanup behavior for rows that do
contain a terminal token.
In `@algorithms/MDLMDec/load_standalone_model.py`:
- Around line 2-5: Update PROJECT_ROOT in load_standalone_model.py to read from
an environment variable and use the denovo_base installation location configured
by container.def as its default, removing the developer-specific hardcoded path
while preserving the existing sys.path insertion and import behavior.
- Around line 51-52: Update the checkpoint-loading flow in the standalone model
loader to validate the glob result before indexing, raising a clear
FileNotFoundError when no weights file matches; then load the selected
checkpoint with torch.load using weights_only=True before passing it to
model.load_state_dict.
In `@algorithms/MDLMDec/loader_.py`:
- Around line 31-46: Update the intensity-array preprocessing around ab.max() to
handle empty arrays and arrays whose maximum intensity is zero without raising
or producing NaN values; preserve valid normalization and padding for non-empty,
non-zero spectra.
- Around line 322-325: Update the dataloader setup in the loader initialization
to preserve the constructor’s custom_columns argument: assign
self.custom_columns from that argument and pass the wrapped
eval_collate_function, rather than bare collate_fn, to build_dataloader. Replace
the local lambda with a spawn-safe module-level collate wrapper or
functools.partial so custom columns work with multiple workers.
- Around line 308-314: Update the dataset filter in the loader to compare the
stored peptide_length field against pep_length bounds instead of measuring the
padded tokenized_sequence. In map_fn, truncate over-length peptides before
padding so every resulting tokenized_sequence retains the expected fixed shape
for collate_fn and np.stack.
- Around line 269-294: Move the partition_modified_sequence assignment to
self.tokenizer before defining lambda_function and invoking the dataset map
operation, ensuring map_fn can access the tokenizer during eager evaluation or
feature inference.
- Around line 277-279: Update the remove_columns handling in _load_dataset to
stop accessing the nonexistent dataset['val'] split; derive removal columns only
from the train split while preserving filtering against available feature names.
In `@algorithms/MDLMDec/mgf_to_parquet.py`:
- Around line 194-197: Update the conditional in the row-building logic to check
the sequence key produced by gather_file_md, while continuing to populate the
modified_sequence output column and append dic['sequence']; ensure this enables
the downstream map_fn tokenization path.
- Around line 163-179: Update main’s file-processing loop to support MSP inputs:
use the MSP metadata keys produced by gather_file_md, including an appropriate
precursor-mass mapping instead of assuming dic['mass'], and parse each peak line
using only its first two whitespace-separated fields so optional annotations do
not cause unpacking errors. Preserve the existing MGF behavior.
- Around line 117-127: Update the file-type handling in the MGF conversion
function to validate the extension before entering the read loop and raise
NotImplementedError for unsupported types. Guard the final-spectrum cleanup
around spectra so empty or header-only inputs return an empty result without
calling max() on an empty mapping; preserve cleanup for non-empty results.
- Around line 155-205: Initialize title, scan_number, retention_time, and
modified_sequence in rows before iterating spectra, and append each spectrum’s
value or None when absent so every column remains aligned. Ensure these columns
are present for every file and preserve consistent ordering/types for the fixed
ParquetWriter schema across subsequent write_table calls.
In `@algorithms/MDLMDec/output_mapper.py`:
- Around line 42-49: Update the spectrum mapping in the output mapper to use a
file-qualified identity rather than title alone, preserving filename and index
(or filename and title) from input through Parquet output. Modify the
title2spec_idx mapping and the output handling around the relevant mapper
methods so duplicate titles across MGF files cannot overwrite each other or
receive predictions from the wrong file.
- Around line 38-45: Update the file-name normalization in the output mapper to
remove only the .mgf suffix using os.path.splitext(), preserving any other dots
in names such as sample.run1.mgf. Keep fn_dict and the subsequent filename
construction based on the preserved stem.
- Around line 184-195: Update the output_data preparation before the aa_scores
serialization to exclude rows with empty sequence predictions (and their
corresponding empty aa_scores), or convert them to the established explicit
no-prediction value so _parse_scores() never receives an empty string for float
conversion. Preserve valid predictions and the existing output columns.

site:pytorch.org torch.load weights_only parameter introduced version
💡 Result:
The weights_only parameter for torch.load was introduced in PyTorch 2.1 [1]. Since its introduction, the parameter was used to allow users to restrict the unpickler to only load specific types (such as tensors, primitive types, and dictionaries) to mitigate security risks associated with the standard pickle module [1][2]. Starting in PyTorch 2.4, warnings were issued regarding the future default behavior of this parameter [2]. The default value was subsequently changed from False to True beginning with PyTorch 2.6 [3][2].

Require a fixed sequence limit.
If a caller sets pep_length=None, Line 233 assigns max_seq=None. map_fn() then evaluates max_seq - peptide_length and raises TypeError for an example with modified_sequence. Reject None at construction, or provide a fixed model sequence limit before mapping.
