The selected type controls the additional structured fields shown in the form. The descriptions below follow the same groups and order as the Type dropdown.

Anesthesia, Drug and Fluid Administration

Administration of anesthetics, sedatives, analgesics, antibiotics, anti-inflammatories, fluids and other substances to a subject, whether as clinical care or as the experimental treatment.

• Analgesic: The administration of a pain-relieving agent, such as buprenorphine or meloxicam. Use this for systemic analgesia given before, during, or after a potentially painful intervention. Structured fields: administered volume, administration route (required), and indication. The body-weight dose is recorded on the active-agent material row.
• Anesthesia: The administration of anesthetic agents to induce unconsciousness, analgesia, or sedation. This entry captures anesthetic protocol details and can stand alone or support a larger procedure episode. Structured fields: anesthetic depth, end time, total duration, recovery time, monitoring, and supportive care. Induction, maintenance, top-ups, reversal and emergence are recorded as stages, each with its route, delivery method, gas concentration, volume, rate and duration; the agents sit inside their stage.
• Anti-inflammatory: The administration of a corticosteroid, NSAID, or another agent to reduce inflammation. Structured fields: administered volume, administration route (required), indication, and administration role. The agent and its body-weight dose are recorded on the active-agent material row.

• Drug administration (other): Use this catch-all only for medication that does not fit a dedicated type, such as a hormone, reversal agent, antidote, or supplement. File by why the drug was given, not by what the drug is: meloxicam for pain is an analgesic, not a drug administration. Structured fields: purpose (required), administration role, administered volume, and administration route (required). The body-weight dose is recorded on the active-agent material row.
• Fluid therapy: The administration of a physiological solution, such as saline or Ringer's solution, for hydration or volume support.

The initial add form asks for the Type, Subject, and required type-specific details. Materials can also be entered before the Procedure is first saved. Select Create and continue to open the full form and complete its optional context, coordinate information, and related entries.

Type of procedure Required Choice

Select the action recorded by this row. The selection controls the Procedure details and which coordinate, region, equipment, and material options are relevant. The type cannot be changed after Material usage entries have been added because the type determines the valid material policy.

Subject Required Single selection

Select the subject on which the action was performed. The choices are limited to subjects in projects where you can make changes, and the selected subject determines the Procedure's project permission context.

Procedure details Varies by type Structured details

Structured fields defined by the selected Procedure type. Required fields, choices, units, and conditional fields vary by type. Use these fields for information that should be searchable and comparable; use Notes only for relevant information that has no structured field.

Coordinate system Required when shown Choice

Select how the Procedure location is referenced. Available systems may be restricted by the Procedure type. The selected system controls the fields shown under Coordinates.

Coordinates When applicable Structured details

Enter the position and orientation of the action using the selected coordinate system. Coordinates may be hidden when they do not apply to the selected Procedure type.

Status Choice

Performed is the default and means this record describes what was done. Planned means the procedure is prepared ahead of time and nothing has happened yet: the page carries a banner, the title says "Planned", and the row is left out of counts, exports and API listings unless asked for. Mark it as performed from the banner once it has happened; the subject must be enrolled first. Cancelled keeps a dropped plan for the record.

Date and time of the procedure Date and time

Record the onset date and time of this individual action. The Procedure episode, when used, provides the broader intervention timing.

Procedure episode Single selection

Associate the action with its broader intervention and compliance episode. The episode and Procedure must refer to the same Subject.

Equipment When applicable Multiple selections

Setup is an optional form-only filter for this field; it is not stored on the Procedure. Select reusable Equipment used to perform the action. Only setups you can change and the Equipment they contain are offered. Equipment describes the working apparatus; materials used or installed belong in Material usage.

Target regions When applicable Multiple selections

Atlas is an optional form-only filter for this field; it is not stored as another Procedure relationship and starts from your preferred atlas. Select the anatomical regions targeted by the action from the active Atlas. This field may be hidden when an anatomical target does not apply to the selected Procedure type.

Licenses Multiple selections

Select the authorizations that cover this particular Procedure. You can add licenses for which you have change access; existing selections remain visible when editing older entries.

Protocol Single selection

Select the written method, SOP, or other documented protocol followed for this action. This is a reference only: it does not populate Procedure fields; use a Procedure template when form values should be reused. Only Protocols classified for Procedures are shown. A Protocol restricted to particular Procedure types is available only when it includes the selected type, while a Protocol without type restrictions can be used for any Procedure type. You can select Protocols you have change access to; a Protocol already recorded on an older entry stays available when you edit it, even if your access has since changed.

Performed by Single selection

Identify the person who physically performed the Procedure, which can differ from the user who entered the information. Eligible users come from the subject's project context; the current user is suggested when no performer has been recorded.

Notes Text · 500 characters

Record complications, adverse events, deviations, or other relevant detail that is not captured by the structured fields.

Material usage Ordered list

Add ordered entries for the materials actually used, such as a stock lot, catalog consumable, or manual material. Each row stores that material's contribution to the action; an overall measure can remain in Procedure details. See the Material usage tab for all source, type, ordering, association, and permission fields.

Stages When the type declares them Ordered list

Some types divide the action into ordered stages: an anesthetic has an induction and a maintenance stage, a perfusion fixation a flush and a fixation stage. Each material row then names the stage it took part in, so the stage's shared conditions are recorded once and the agents point at it. Stages and their materials are edited together on the Materials tab.

Choose the system that matches how the position was measured. An absolute system stores three position axes in one fixed frame. A surface coordinates with depth system stores two surface-plane coordinates and a depth measured from a local surface. Angle fields describe the approach and rotation around the insertion axis.

External coordinates

• External XYZ Coordinates with Euler Orientation: Uses X, Y, and Z positions plus ordered fixed-frame X, Y, and Z rotations. Name the external frame and define its origin, positive axes, handedness, and unrotated pose.
• External XYZ Coordinates with Quaternion Orientation: Uses the same physical XYZ frame plus a canonical Hamilton W/X/Y/Z quaternion for device orientation. Choose it for software- or sensor-derived poses where Euler angles are unsuitable.

Stereotaxic coordinates

• Stereotaxic Bregma-Based Absolute Coordinates: Uses AP, ML, and DV coordinates and their angles in a fixed Bregma-referenced frame. Choose it when DV is an absolute coordinate rather than a surface-zeroed depth.
• Stereotaxic Bregma-Based Surface Coordinates with Depth: Uses Bregma-referenced AP and ML coordinates, depth from the brain surface, AP and ML angles, and insertion-axis rotation. Choose it when depth was zeroed at the brain surface.
• Stereotaxic Lambda-Based Absolute Coordinates: Uses AP, ML, and DV coordinates and their angles in a fixed Lambda-referenced frame. Choose it when Lambda is the origin and DV is an absolute coordinate.
• Stereotaxic Lambda-Based Surface Coordinates with Depth: Uses Lambda-referenced AP and ML coordinates, depth from the brain surface, AP and ML angles, and insertion-axis rotation. Choose it when Lambda is the origin and depth is surface-zeroed.

Landmark-referenced coordinates

• Landmark-Referenced AP/ML/DV Absolute Coordinates: Uses AP, ML, and DV coordinates and their angles relative to a selected landmark. Choose it when the origin is not fully covered by the Bregma or Lambda systems, and describe custom landmarks.
• Landmark-Referenced AP/ML Surface Coordinates with Depth: Uses landmark-referenced AP and ML coordinates, depth from a selected surface, AP and ML angles, and insertion-axis rotation. Choose it when the landmark and depth surface are separate references.

Spinal coordinates

• Spinal RC/ML/DV Absolute Coordinates: Uses rostrocaudal (RC), mediolateral (ML), and dorsoventral (DV) coordinates and their angles in a spinal frame. Choose a spinal segment, vertebral level, or custom origin and identify the level.
• Spinal RC/ML Surface Coordinates with Depth: Uses spinal RC and ML coordinates, depth from a selected surface, RC and ML angles, and insertion-axis rotation. Choose it when depth was zeroed at the dura, pia, cord, or a custom surface.

• NIMH Macaque Template v2 XYZ Absolute Coordinates: Uses physical distance from ear bar zero in the NMT v2 stereotaxic frame: X increases rightward, Y anteriorly, and Z superiorly. AP and ML angles describe the ordered approach tilts, followed by rotation around the insertion axis.
• Brain/MINDS Marmoset Atlas 2.0 XYZ Absolute Coordinates: Uses physical millimetres from the BMA 2.0 atlas origin, which lies between the commissures and is not ear bar zero: X increases rightward, Y anteriorly, and Z superiorly. AP and ML angles describe the ordered approach tilts, followed by rotation around the insertion axis.
• mapzebrain Larval Zebrafish XYZ Absolute Coordinates: Uses physical micrometre distance from the mapzebrain standard-brain volume corner: X increases rightward, Y posteriorly, and Z superiorly. Y and X angles describe the ordered approach tilts, followed by rotation around the insertion axis. Values are physical coordinates, not voxel indices.
• JRC2018 Unisex Fly Brain XYZ Absolute Coordinates: Uses physical micrometre distance from the JRC2018 unisex template volume corner: X increases toward the fly's left, Y ventrally, and Z posteriorly.

Physical and Health Logs

• Monitoring log: Routine measurement of body weight, intake, and condition. This is the type to use for ordinary weight tracking. Each entry must record at least one of its values — an entry that measures nothing is rejected. Entry fields: weight, food consumed, water consumed, body condition score (1–5), and health observations.
• Welfare check: A structured welfare assessment against defined endpoint criteria. Use this rather than Monitoring when the point of the check is clinical judgement and humane endpoints. Entry fields: clinical signs, actions taken, condition and demeanour (0–4), monitoring plan, pain scoring method and score, procedure or wound site type, site observation, endpoint criterion, and whether humane endpoint criteria were met.

• Wellness log: A free-text health stream. Deprecated: use Welfare check for new health records. Legacy entry field: wellness.

The initial add form asks only for the type and subject. Select Create and continue to add the protocol and description, and to start recording entries.

Type Required Choice

What this stream records. It fixes the structured fields every entry in the log will offer, so a stream cannot mix two kinds of observation — start a second log instead.

Subject Required · fixed after creation Single selection

The subject this stream belongs to. It supplies the log's project permission context, and it becomes read-only once the log exists, so a series of observations can never be reattributed to a different animal.

Protocol Single selection

The documented method followed for entries in this stream. Only Protocols classified for subject logs are offered, and a Protocol restricted to particular log types appears only when it covers the selected type. You can select Protocols you have change access to.

Description Text

What this series is for and how to read it — the measurement context shared by every entry. Per-occasion remarks belong in the entry's own notes.

Each entry then records its own date and time (required), the person who performed it, an optional episode phase, free-text notes, and the structured values defined by the log's type.
