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 filters: File path, 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, and Object appears only on the Light subtype. Each filter narrows the list as you type. Clear resets all of them at once and shows how many are active.

File path matches any part of a frame’s full path, folder names included, so typing a project folder’s name isolates every frame stored under it. It is also the one filter that finds an Unclassified file, which usually has no other header to match on. Object matches any part of the object header; each light row also shows its object name under the file name.

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.

Selecting frames on a flat list

The checkbox in the table header selects every frame on screen. A long list loads as you scroll, so when more frames match the filters than are on screen, a line above the table reads how many of the matching frames are selected and offers Select all matching. That extends the selection to every frame the current filters match, loaded or not; frames that scroll in later arrive already selected, and the bottom bar and the editor’s Apply button both show the full matching count. Clear selection on the same line empties the selection. Changing a filter, a tab, a subtype pill, or the Rejected switch empties it as well, so an action only ever covers frames you can see the filters for.

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.

When every selected row is a light, the same editor offers two more fields, Object and Filter, for correcting what the capture software wrote. A field left blank is left alone on every frame. Setting a new object name moves the selected frames to that target: the Targets list re-groups on the next read, the moved frames lose their alignment fits and are screened again on the new target, and a session that contained them lists them under the new name. Changing the filter moves the frames to that filter’s tab on their target. See why do I have two M31 cards for the case where one object name spans two projects.

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?.
