Where do I see everything at once, and how do I fix files that didn't classify?

Artifact is the umbrella term for anything cataloged: a raw frame, a master, or a stack. This page says frame or master wherever one is meant, and artifact only where the point covers both.

Open Artifacts from the library nav for a single table of everything in the catalog, cut by category and subtype, with the tools to fix what came in wrong.

Screenshot: The Artifacts page in the Frames category, Bias subtype, with several groups expanded.

Category and subtype

Three tabs sit at the top: Frames, Masters, Unclassified. Under Frames or Masters, four pills narrow further by subtype: Bias, Dark, Flat, Light. Unclassified has no subtype pills; it is a single bucket of everything that could not be classified.

Frames × Bias/Dark is the one perspective that groups: matching frames collapse into a stackable group with a frame count, rather than listing every file. Every other combination (Frames × Flat/Light, Masters of any subtype, Unclassified) is a flat, paged list. A note under the Light and Flat perspectives points to Sessions or the target’s filter tab for actually reviewing or aligning a night; Artifacts is for bulk management, not inspection.

The filter bar

Below the category tabs sits a Rejected control, and under it a row of match filters: Instrument, Camera ID, Gain, Offset, Readout, X Bin, Y Bin, Width, Height, ISO, USB. Two more, Exp (s) and Set °C, appear only on the Dark subtype. Each filter narrows the list as you type. Clear resets all of them at once and shows how many are active.

The rejection lens

Rejected is a three-way switch: Active (the default, rejected artifacts hidden), Include (rejected artifacts shown alongside active ones), and Only. Only is the cleanup lens: it shows nothing but rejected artifacts and adds a Delete all Rejected button, which gathers every rejected artifact matching the current filters and asks you to type the exact count before it unlocks. Deletion is permanent. See rejecting versus deleting.

Grouping by match signature

Under Frames × Bias or Frames × Dark, a folder of mixed captures sorts itself automatically: every frame sharing the same camera signature, instrument, gain, offset, readout mode, binning, and for darks exposure and set temperature, collapses into one group. Expand a group to see its individual frames, or select the whole group at once to stack it. A group is labeled by the values it shares; a group missing enough of them to be genuinely unmatchable is called out with a banner above the table, and each such group carries its own Set match fields button next to its readiness chip.

Selecting frames or a whole group opens a bottom bar with Reject, and, on the grouped Bias/Dark view, Stack → to build a master from the selection.

Fixing what went wrong

Two controls force EigenFrame to re-read a file from disk and reclassify it:

Reindex, on an individual row in the Unclassified view, re-parses that one file’s header.
Reclassify all errored, a bulk button above the Unclassified list, re-reads every file currently stuck in a read error at once.

For masters that arrived without the fields calibration matching needs (common for a master built outside EigenFrame, which typically carries none of the camera-signature header), select one or more rows, or an entire group, and use Edit / reclassify (or a group’s own Set match fields) to fill in instrument, gain, offset, readout, binning, and the rest by hand. See how calibration is assigned for what each of those fields does and how a missing one affects matching.

Where Unclassified comes from

A file lands in Unclassified for one of two reasons:

The header could not be read at all. The row carries a warning icon with the reason, and Reindex or Reclassify all errored is the fix once the underlying problem (a damaged file, an unsupported variant) is resolved.
The header read fine but lacks the keywords that distinguish Bias, Dark, Flat, and Light. This is common on masters and on captures from software that does not write a type keyword. Reindex will not help here, since the file already read correctly; set the type yourself, either per file or, better, at the source.

Fixing it at the source means the folder’s Override, which stamps every file scanned under it going forward, or its import rules, which can target specific paths and also re-apply to records already cataloged. See library folders and import rules for both. If the files are one-shot-colour, Bayer, or camera raw, an override will not help; see will EigenFrame read my data?.
