02 / Detection summary

File detected successfully

- Detection confidence

Experiment nameUsed for downloads as growth_curve_<data_stage>.csv. Original instrument metadata is preserved.

Why was this format detected?

03 / Standardized data

raw_measurements preview

First 8 rows

Each row represents one well x one time point x one measurement channel. Original time labels, well names, and instrument-provided content labels are preserved when present.

04 / Plate map

Describe your experimental plate

Import metadata or keep assigning it manually. Both paths update the same reviewable plate_map.

Plate layout

Confirm plate size

Optional metadata import

Upload .xlsx or .csv

Required columns: well, strain, condition, replicate_id, role, blank_group.

CSV files cannot contain dropdowns. In CSV metadata, role must be one of: sample, blank, control, unused.

Click or drag to select wells. Hold Shift, Command, or Ctrl to add groups. Row and column labels select whole rows or columns. Dim wells have no raw measurement but may still receive metadata.

Separate metadata table

plate_map preview

well	sample_id	condition	replicate_id	role	blank_group

plate_map remains separate from raw_measurements.

05 / Blank correction

Generate processed measurements

Choose how raw sample and control curves should be processed. Blank wells are used for correction and unused wells are excluded.

Correction methodMean of matching blank wellsMatch using blank_group and subtract the time-point mean.No blank correctionKeep raw values without background subtraction.

Replicates remain individual rows. raw_measurements and plate_map are preserved separately.

07 / Growth parameters

Replicate-level parameter analysis

Run the validated browser-side gcplyr engine on every eligible sample and control curve.
