Runs an arbitrary user script against one or more materials. The script, its dependency list and any data files it reads are set in the params cells, uploaded to the account's object storage, and fetched onto the compute node by the Custom Python Script workflow from Standata. The script reads material.json, settings.json and its own files by relative path, and whatever it prints comes back as the result. Section 9 re-runs the saved workflow with different settings and no re-upload. The script is uploaded as a file rather than inlined into the workflow, so it is never passed through the template engine and reaches Python exactly as written. Adds a notebooks_utils file helper for the uploads, plus the fixed runner and an input setter that matches execution unit inputs by template name rather than position. Also fixes load_materials_from_folder, which built every material in one comprehension: a single file that is not a material raised out of the whole call, so a user dropping a data file their script reads into uploads/ broke material loading for every calculation notebook. One material lacking build metadata also silently downgraded all the others. Each file is now built on its own and anything no material class accepts is skipped with a warning.

notebooks_utils.io imports IPython eagerly through pyodide.io, so any test importing a module that reaches it for get_data or set_data - core.entity.material.io among them - fails to collect with ModuleNotFoundError under CI, which installs only ".[tests]". IPython was declared in the jupyterlite extra alone. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Review feedback on #360. An entry in USER_ASSET_FILES named user_script.py silently replaced the script, and a missing asset raised a bare FileNotFoundError that named neither the file nor the parameter to fix - a trap hit during development. RESERVED_FILENAMES also covered only the two files the execution unit renders, not material.json and settings.json, which the runner writes after the IO unit has fetched the uploads. An asset under either name was replaced at run time with no warning. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The assign-settings unit is gone from the standata workflow: SETTINGS now travels as a settings.json uploaded next to the script and fetched by the same io unit. The chain drops to four units, the runner writes only material.json, and reusing a saved workflow no longer edits the workflow at all - upload a new settings.json over the old key and submit. settings.json leaves RESERVED_FILENAMES accordingly: the workflow no longer writes it, the notebook uploads it.

The workflow stays in the collection pointing at the uploaded files, runnable from the UI or another notebook against any material; changing parameters is uploading a new settings.json. A dedicated demo section with its own REUSE_* params was scaffolding, not something a user needs. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
For settings.json the error claimed the script used that name; the conflict is the notebook's own settings upload. Review feedback on #360. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Closes the review blocker on #360. The upload payload shape, the reserved-name refusal, and to_object_storage_input were verified only by a three-minute cluster run; to_object_storage_input in particular is a pure function whose five fields rupy requires with no defaults. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…faults The notebook shipped with one worked example baked into its defaults - a radii table as a data file, a cutoff_scale setting uploaded as settings.json, and a 40-line coordination-number script - which read as required machinery rather than as an example. The defaults are now the minimum a custom calculation needs: one material, no data files, no dependencies, and a stdlib-only script that reports the elements, the atom count and the cell volume. settings.json is gone; a script's parameters belong in the script, which sits in its own cell. USER_ASSET_FILES and USER_REQUIREMENTS keep the mechanisms, with an example in a comment. The Cypress feature covers the richer path by overriding both cells.

…d as bytes Asset files were opened in text mode, so a binary file died on a decode error inside the read and text-mode newline translation meant the upload was not byte-for-byte the file. Reading bytes and decoding UTF-8 strictly fixes both: the upload is verbatim, and a binary file now fails with a message that says where such a file goes instead. An upload travels as a string in a JSON body, so the text-only contract is a property of the endpoint, not a notebook choice. It is stated where the parameter is set, and §4.1 carries the two-line recipe for a file already sitting in the object storage folder - too large or not text - which USER_ASSET_FILES cannot cover. Raised by CodeRabbit on PR #360.
The example Vsevolod asked for on 2026-08-23: upload a custom pseudopotential (Si.upf, ONCVPSP NC PBE, ships in uploads/) through the files endpoint and run a Quantum ESPRESSO band structure for Si that consumes it - driven entirely from Python. Three verified pieces line it up, none of them new platform machinery: - pw templates render pseudo_dir = JOB_WORK_DIR/pseudo; - an object_storage io unit with pathname "pseudo" fetches the upload exactly there (rupy joins work_dir/pathname/basename), and survives job creation intact; - the ATOMIC_SPECIES cards are pointed at the file by the documented expert-mode input edit with isManuallyChanged, which survives job update while a method.data.pseudo edit does not (formMethodData re-resolves it from metaProperties on every create and update - probed, not guessed). to_object_storage_input grows an optional pathname (default keeps current behaviour); unit-tested. The io-unit attachment is idempotent across re-runs. The Cypress feature asserting the consumed inputs name Si.upf is in web-app. The local runtime gate is queued behind the compute broker, which is currently unreachable (app-side SYN_SENT, heartbeats stopped 08-21); results will be reported when it returns.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Fail with a clear message when no cluster matches.
If CLUSTER_NAME matches no hostname, cluster is None. Line 508 then raises an AttributeError on compute.cluster.hostname. If clusters is empty, line 501 raises an IndexError. Both hide the real cause from the notebook user. The same pattern was flagged in other/materials_designer/workflows/custom_python_calculation.ipynb.
🛡️ Proposed fix
if CLUSTER_NAME:
cluster = next((c for c in clusters if CLUSTER_NAME in c["hostname"]), None)
+ if cluster is None:
+ raise ValueError(f"No cluster matches CLUSTER_NAME='{CLUSTER_NAME}'. Available: {[c['hostname'] for c in clusters]}")
else:
+ if not clusters:
+ raise ValueError("No clusters are available for this account.")

Compute: handle an unmatched CLUSTER_NAME and an empty clusters collection by
raising a clear user-facing error, while preserving the existing
selected-cluster behavior for valid input. Apply the same validation to the
corresponding cluster-selection flow in custom_python_calculation, anchored to
the cluster assignment and Compute construction.
…PECIES card The bare multiline "element number token" pattern also matches ATOMIC_POSITIONS lines, where it overwrote the second coordinate with the filename - reproduced on a real rendered input: "Si 0.000000000 Si.upf 0.000000000". The substitution now runs only on the ATOMIC_SPECIES card slice, and the check against a real job document full-diffs the input: exactly one token changes per pw unit. Raised by CodeRabbit on PR #360 (a genuine catch - the earlier verification asserted the SPECIES card and never diffed the rest).

Detect the next card header instead of using a blank line as the boundary.
If ATOMIC_SPECIES is followed immediately by ATOMIC_POSITIONS, rendered.find("\n\n", start) returns -1, so end becomes the end of the full input. The regex can then replace a positive PSEUDO_ELEMENT coordinate in ATOMIC_POSITIONS with PSEUDO_FILE, reintroducing the previous input-corruption bug. Quantum ESPRESSO defines ATOMIC_POSITIONS as a separate keyword-introduced card, so use card headers to determine the boundary and add a regression test with adjacent cards. (quantum-espresso.org)

…saved workflow The first live run failed at §4.5: PATCH /workflows/:id 500s for an API-created workflow because the update handler scopes its lookup to workflows inSet of the caller's sets - a bank-copied workflow is in the account's set, a created one is not (ENTITY_NOT_FOUND surfaced as the known null-return 500). Reproduced against the live instance; the earlier probe had validated the update on a bank copy only. The io unit is now inserted into the workflow config before Workflow.create, so the single create call stores the complete four-unit workflow - verified live: created workflow carries io-pseudo at head, and a job from it renders with the chain intact. Also switched the save from get_or_create_workflow to a plain create: the list query the helper filters by is ignored by the platform (recorded finding), so its "reuse" can return an arbitrary workflow - observed returning a Total Energy workflow - which would silently drop the io unit.
…on_calculation Per Vsevolod: "It needs to be custom python! Not separate arbitrary thing. We upload pseudo thru it, we run the QE job with it. That's the idea." band_structure_custom_pseudopotential.ipynb is deleted; its verified mechanics move into custom_python_calculation.ipynb as section 9: upload Si.upf through the same upload call as section 4.1, prepend the io unit that fetches it into the job's pseudo directory, point the ATOMIC_SPECIES cards at it, run the Quantum ESPRESSO band structure, print the consumed cards and plot the bands. One notebook, one upload path, and the example demonstrates that an upload is an ordinary platform file any application can consume. TOC entry for the separate notebook removed.
…tension CodeRabbit's follow-up on the card-slice approach was right that a blank line is a fragile boundary: cards touching each other would leak the substitution into ATOMIC_POSITIONS again. Requiring the replaced token to be a UPF filename kills the whole class without slicing - position lines end in numbers, never ".upf" - and drops four lines. Verified by full token diff on real rendered inputs and on a synthetic no-blank-line variant.
…seudopotential demo Per Vsevolod: the QE-with-uploaded-pseudo example runs through a custom SHELL notebook that does what the python one does, "with a difference in app used and the body". custom_python_calculation.ipynb reverts to its clean 37-cell state (section 9 and the rendered-input patching die here); the new custom_shell_calculation.ipynb mirrors it cell for cell on the new standata Custom Shell Script workflow. The default body is the correction's example end to end: upload Si.upf through the notebook's own upload cell, build pw.x inputs from material.json with pseudo_dir './', module add espresso, run SCF + bands (the invocation is the platform's own job_espresso_pw_scf.sh precedent), and print QE's own proof line - "read from file: ./Si.upf" - plus the band edges at Gamma as JSON. The shell runner (CUSTOM_SCRIPT_RUNNER_SH) writes material.json and *sources* user_script.sh so `module` stays available. hello_world.sh, its on-disk name, joins RESERVED_FILENAMES (tested). Input building verified locally against the real Silicon material: valid pw inputs, ATOMIC_SPECIES names Si.upf.
…H, not cwd First live run of the shell runner died with ". user_script.sh: file not found": the dot builtin looks the operand up in PATH and the working directory is not on it. "./user_script.sh" is unambiguous in both POSIX and bash modes.
…oof line The calculation itself was already correct on the first complete run - modules loaded, both pw.x steps finished, gamma_direct_gap_ev 2.544 eV, the PBE value for Si - but QE 6.3 wraps "PseudoPot. # 1 for Si read from file:" with the filename on the next line, so the bare grep dropped the very token the proof is about. grep -A 1 carries it.

Depends on mat3ra/standata#150 — the notebook resolves
custom_script.jsonfrom Standata, so it needs a standata release to run from the published wheel. Verified locally against a standata build. Also pairs with mat3ra/web-app#2960, which adds the upload endpoint.What

No specific simulation app.USER_REQUIREMENTS→ a virtualenv on the compute node;USER_ASSET_FILES→ filenames the user drops in../uploads;SETTINGS→ uploaded assettings.jsonnext to the scriptsettings.jsonand asset files to the account's object storage; §4.2 fetches the four-unit Standata workflow and fills in the objects, runner and requirementssettings.jsonover the old keyThe script is uploaded as a file rather than inlined into the workflow, so it never goes through the template engine and reaches Python exactly as written. On the node it reads
material.json,settings.jsonand its own files by relative path.Default is a single material; the Cypress feature supplies the two-material case, so asserting both Si and C is something the default alone cannot produce.
