+ # The Well for The Cell
38
+
39
+ Version **1.0.0-rc1**, built 2026-10-09T17:33:51+00:00 from wcEcoli commit `60e68057b55926b0771cbb5c788e55a00805ef40`.
40
+
41
+ Time series from the [wcEcoli](https://github.com/CovertLab/wcEcoli) whole-cell model of *Escherichia coli*. Each sample is **one cell generation**: the cell from birth to division (or to the step at which the simulation stopped), recorded every **1 s** of simulated time. Lineages are simulated for several generations, and the samples of one lineage are linked by `parent_id`. The 117,174 trajectories come from 31,101 lineages of 3,896 distinct cells (design x condition), grouped into five families by campaign tier.
42
+
43
+ | family | tier | what varies | cells | lineages | trajectories |
44
+ |---|---|---|---:|---:|---:|
45
+ | `wildtype_media` | T1 | wild-type cells in a range of static media | 21 | 168 | 641 |
46
+ | `single_knockout` | T2 | single-gene knockouts across media | 2,752 | 21,949 | 83,937 |
47
+ | `dynamic_media` | T3 | media shifts and sinusoidal media schedules | 684 | 5,472 | 18,599 |
48
+ | `regulation` | T4 | transcription-factor activity and ppGpp set-point perturbations | 64 | 512 | 2,046 |
49
+ | `double_knockout` | T5 | two-gene knockouts | 375 | 3,000 | 11,951 |
50
+ | **total** | | | 3,896 | 31,101 | 117,174 |
51
+
52
+ ## What is in this repo
53
+
54
+ Which families of each config are uploaded here (size on the Hub):
55
+
56
+ | family | trajectories | `core` | `expression` | `metabolism` | `expression_1s` | `metabolism_1s` |
57
+ |---|---:|---|---|---|---|---|
58
+ | `wildtype_media` | 641 | yes (103.0 MB) | yes (512.4 MB) | yes (502.3 MB) | not in this release | not in this release |
59
+ | `single_knockout` | 83,937 | yes (13.5 GB) | not yet | not yet | not in this release | not in this release |
60
+ | `dynamic_media` | 18,599 | yes (2.8 GB) | not yet | not yet | not in this release | not in this release |
61
+ | `regulation` | 2,046 | yes (323.9 MB) | not yet | not yet | not in this release | not in this release |
62
+ | `double_knockout` | 11,951 | yes (1.9 GB) | not yet | not yet | not in this release | not in this release |
63
+
64
+ `expression` and `metabolism` are currently available for `wildtype_media` only; `single_knockout`, `dynamic_media`, `regulation` and `double_knockout` will be added in a later upload. `expression_1s` and `metabolism_1s` (1 s matrices, ~1.3 TB estimated) are not in this release.
65
+
66
+ `index.parquet` lists every trajectory, uploaded or not. Its locator columns (`<config>_file`, `<config>_row_offset`, `<config>_n_rows`) are null for data not in this repo, so `index["<config>_file"].notnull()` (e.g. `index.expression_file.notnull()`) is the authoritative availability check. `load_dataset(..., "<config>", split="<family>")` fails for a family that has not been uploaded (e.g. `load_dataset(..., "expression", split="single_knockout")` until that family is uploaded).
67
+
68
+ ## Configs
69
+
70
+ Each config is one data product. Every config carries `sample_id`, `t`, `t_abs` and the 18 scalar channels; the matrix configs add per-gene or per-reaction columns. `expression` and `metabolism` keep the rows with `t % 10 == 0` plus each trajectory's last row (point samples, not averages); `expression_1s` and `metabolism_1s` keep every row. The split of every config is the family.
71
+
72
+ | config | rows every | matrices (active columns) | trajectories | rows | size |
73
+ |---|---|---|---:|---:|---:|
74
+ | `core` | 1 s | scalars only | 117,174 | 316,751,845 | 18.6 GB |
75
+ | `expression` | 10 s | `mrna_counts_matrix` (2,773), `protein_counts_matrix` (4,174) | 641 (wildtype_media only) | 173,523 | 512.4 MB |
76
+ | `metabolism` | 10 s | `reaction_flux_matrix` (3,974), `exchange_flux_matrix` (82) | 641 (wildtype_media only) | 173,523 | 502.3 MB |
77
+ | `expression_1s` | 1 s | `mrna_counts_matrix` (2,773), `protein_counts_matrix` (4,174) | not in this release | | |
78
+ | `metabolism_1s` | 1 s | `reaction_flux_matrix` (3,974), `exchange_flux_matrix` (82) | not in this release | | |
79
+
80
+ Matrix columns are pruned to the columns that are non-zero at least once anywhere in the campaign (active columns: mrna_counts 2,773 of 3,133, protein_counts 4,174 of 4,310, reaction_flux 3,974 of 9,612, exchange_flux 82 of 87). The full column lists, with an `active` mask and each active column's position in the product (`product_column`), are in `provenance/reference/<matrix>.parquet`.

187

189

190
+ ```
191
+
192
+ One trajectory by its locator (reads only the row groups it spans):
193
+
194
+ ```python
195
+ import pyarrow.parquet as pq
196
+ from huggingface_hub import hf_hub_download
197
+
198

+ table = pq.read_table(path, filters=[("sample_id", "=", row["sample_id"])])
201
+ assert table.num_rows == row["expression_n_rows"]
202
+ ```
203
+
204
+ ## Ids
205
+
206
+ - `cell_id` is the campaign experiment name, slugified, with the tier as a plain `T1`..`T5` prefix: `[T2_CORE] argG_KO/basal` becomes `T2/argG_KO/basal`. The raw name is in `experiment_name`.
207
+ - Regulation (T4) transcription-factor cells are the exception: the campaign named them from the sorted TF *symbols* while the simulator indexes the sorted TF *ids*, so their experiment names name the wrong TF (`[T4] araC/active` ran trpR). Their `cell_id`, `tf_target` and `tf_target_id` use the TF that actually ran (`T4/trpR/active`); `experiment_name` keeps the campaign's name.
208
+ - A knockout removes a whole transcription unit: the model sets the expression of one TU to zero, so other genes of that TU are silenced too. `knockout_genes` lists the targeted genes, `knockout_tu_ids` the TUs actually knocked out.
209
+ - `lineage_id = cell_id + "/s{seed}"`; `sample_id = lineage_id + "/g{generation}"`, e.g. `T1/WT/acetate/s0/g0`.
210
+ - `parent_id` is the previous generation's `sample_id` (null at generation 0).
211
+
212
+ ## Time axis
213
+
214
+ - Steps are 1 s. `t` restarts at 0 for every generation; `t_abs` continues across the generations of a lineage, so generation g+1 starts where generation g ended.
215
+ - Row 0 is the birth state: the daughter at half the mother's mass. `growth_rate` is null at row 0 (no step has been taken yet).
216
+ - Only one daughter is followed at each division, so a lineage is a chain, not a tree.
217
+ - A generation stopped by the per-generation time limit (`TimeLimitReached`) has 10,801 steps (0..10,800 s).
218
+
219
+ ## Outcomes
220
+
221
+ `divided` is true when the cell divided. `terminated` marks the generation in which the lineage ended, and `termination_class` says why:
222
+
223
+ | termination_class | meaning | trajectories |
224
+ |---|---|---:|
225
+ | `none` | divided normally | 112,545 |
226
+ | `time_limit` | reached the time limit without dividing: the only clean non-division (slow or arrested growth) | 1,973 |
227
+ | `negative_counts` | a molecule count went negative (numerical failure) | 2,647 |
228
+ | `fba_infeasible` | the metabolism FBA problem had no solution | 3 |
229
+ | `equilibrium_unstable` | the equilibrium solver failed | 6 |
230
+ | `other` | any other simulator exception | 0 |
231
+
232
+ `time_limit` is the only clean non-division; the other classes are solver failures, and the rows before the failure are kept as recorded.
233
+
234
+ ## Suggested tasks
235
+
236
+ 1. **Growth-rate regression from the perturbation**: predict `growth_rate` (index) from the perturbation columns (`knockout_genes`, media, `tf_target`, ...) and optionally the first rows of the trajectory.
237
+ 2. **Viability classification**: predict whether a generation is *not* terminated by the time limit (`termination_class != 'time_limit'`), i.e. whether the perturbed cell still divides.
238
+ 3. **Forecasting**: given the trajectory up to time t, predict the channels at t + h, with horizons h stated in seconds (e.g. 10, 60, 600 s) so 1 s and 10 s products compare directly.
239
+
240
+ Use `split_by_lineage` (train 93,698 / val 11,731 / test 11,745) to hold out whole lineages, or `split_by_gene` (train 91,561 / val 12,627 / test 12,986) to hold out whole genes; both are fixed columns of the index (seed 20261008).
241
+
242
+ ## Provenance
243
+
244
+ - Simulator commits (`index.git_hash`): `18a908d28303c2feeba161e962c049e4f712454e`, `5f5fa5f4fe2302af12385528d176f4d73c4bf3a6`, `c41efd7561d40316e5e83b20e3fb27316845b0bc`, `c462ae99c47d24c327a0311edd785f664d8038bc`, `c47683e19614b17e9c022762a238a1b36aa12dd2`, `ddc88250ad5c3ab07872c46888cd18f0fd3d32e6`, `e319d09f3749168155d246b103b7d37ba492ec63`.
245
+ - Simulation options hashes (`index.sim_options_hash`): `2ba80aae18ba5904625753010432220257822ee442fe87c162cb651d35f5cc0f`.
246
+ - Fitted parameters (`index.parca_cache`, with the sha256 of its `simData.cPickle` in `index.kb_sha256`): `5558948af4ad806f21d7c80c` (sha256 `8ff93a58576f484edfd6fea641eeeb4fc554b52b97da49f4d8b275ca74496667`), `fa6a9ebd4b1c988a36ef9fa1` (sha256 `b1750cf04409c37ebce9d4d3009daeae0779dd66508812c2807744d83baf1ab7`). The Parca caches themselves are not included in this repo (see Licence).
247
+ - Every trajectory ran with operons on and the steady-state tRNA charging model (`trna_charging` true, no kinetic charging), from one of two fitted parameter sets identified by `kb_sha256` and `parca_cache`; do not pool rows across the two parameter sets without checking `kb_sha256`.
248
+ - `provenance/scan_runs.parquet`: every run directory read (32,072 runs), with its generation count and reference-id hash.
249
+ - `provenance/failed_jobs.parquet`: 971 campaign jobs that failed, with the error message and the generations they left behind.
250
+ - `provenance/export_qc.parquet`: the QC verdict of every trajectory in every config (118,456 checks, 0 failed). Trajectories that fail QC are left out of that config.
251
+ - `stats/<family>.parquet`: per product, channel and matrix column: mean, population std, min, max and row count.
252
+ - `manifest.json`: row and byte totals per config, counts per family.
253
+
254
+ Never recorded: `aa_pool_size`, `ntp_pool_size`, `trna_charged_fraction` are in the exporter's channel list but were not written by any simulation, so they are absent from every product.
255
+
256
+ ## Licence
257
+
258
+ CC BY 4.0 for everything in this repo. The wcEcoli model is by the Covert lab (Stanford) and is licensed separately under the Stanford Academic Software License; it is not included here. The fitted parameter sets (Parca caches) are not distributed either and are identified only by `kb_sha256` / `parca_cache`; reproducing these simulations requires obtaining wcEcoli under its own licence.
