Expectations

Organism
Homo sapiens
Assay
bulk RNA-seq
Specimen/source
patient tissue or biopsy
Controls
matched normal, adjacent normal, paired normal, healthy tissue control, or otherwise normal tissue control

Rules

Default filters
Human only; Bulk RNA-seq only; Tumor-normal only; Tissue or biopsy only; Hide biofluid/model systems
Warning rules
missing or unclear control group, unclear disease context, unclear tissue source, mixed sample types, model-system markers, secondary assay context, missing processed data, or small cohort size
Score caps
non-human datasets stay below the primary recommendation band, missing colorectal/colon/rectal/CRC context stays below the primary recommendation band, biofluid and model-system datasets cannot reach Recommended by default, microarray and secondary assays are capped unless explicitly enabled, or small cohorts are capped below high-confidence recommendations
Downgraded contexts
microarray unless explicitly enabled, biofluid-only datasets, cell-line datasets, organoid datasets, xenograft or PDX datasets, non-colorectal disease contexts, or treatment-only experiments

Study Classification

Tumor vs unmatched normal Tissue

Analysis Readiness

Ready after review
94% DE readiness

Contrast completeness

25/25 pts

Both case and control groups are present in the proposed grouping.

Minimum group size

20/20 pts

Each contrast group has at least 2 samples.

Processed data availability

20/20 pts

Processed data is marked available in the GEO index.

Sample decision clarity

15/15 pts

All samples are assigned to a case or control group.

Blocking warnings

7/10 pts

Warnings are present, but none are critical blockers.

Metadata normalization

7/10 pts

Metadata quality is usable, but still deserves review.

Blockers

No readiness blockers detected.

Next Steps

  • Review the sample grouping CSV and contrast CSV before running differential expression.
  • Confirm processed count files and sample identifiers match the exported metadata.

Analysis Preparation Checklist

5/6 ready

Group labels reviewed

Needs review

Siftome proposed case and control labels, but no reviewer confirmation is stored yet.

Open the sample grouping CSV and confirm group labels before analysis.

Minimum sample count met

Ready

Both groups meet the minimum of 2 samples.

Confirm whether the cohort is large enough for the intended statistical analysis.

Processed counts available

Ready

Processed data availability is marked true in the GEO index.

Verify that downloaded processed files contain usable count or expression identifiers.

Ambiguous samples handled

Ready

No review-needed or unassigned samples are present in the proposed grouping.

Still scan the grouping table for biology-specific ambiguity.

Exclusion decisions recorded

Ready

No hard-excluded samples were detected by the current rules.

Record any manual exclusions in the downstream analysis notes.

Source links preserved

Ready

The dataset and sample accessions can be linked back to GEO.

Keep GEO dataset and sample links with exported metadata.

Bioinformatician Review

Bioinformatician review required

Ask a bioinformatician to review grouping, count availability, exclusions, and design before DE.

  • Small cohort warning is present.

Why This Is Ranked Here

Patient tissue tumor-vs-normal
Exploratory only Dataset can inform exploration but is not strong enough for primary analysis.

Score Components

  • relevance 50% Organism normalized. Assay type normalized.
  • comparison suitability 5% Tumor and normal sample groups detected. No excluded sample type flags detected. Tumor/normal design boosted for colorectal tumor-vs-normal tissue triage. Patient tissue or biopsy specimens boosted for tissue comparison triage. Missing colorectal disease context downgraded for tumor-vs-normal tissue ranking.
  • metadata quality 70% Sample source clarity: All samples have source metadata and clear GSE/GSM accessions. Group clarity: Rule-based grouping found both case and control samples. Disease clarity: Disease or condition metadata was not normalized. Tissue clarity: Tissue metadata was not normalized. Treatment clarity: No unclear treatment split detected in the sample metadata. Replicate clarity: No pooled sample or technical replicate flags detected. Data availability clarity: Dataset-level processed or raw data availability is explicit.
  • data availability 100% Processed data available. Raw data available.
  • overall 45% Weighted score: 30% relevance, 30% comparison suitability, 25% metadata quality, 15% data availability. Overall score capped because comparison suitability is weak for the selected search intent. Overall score capped because fewer than six samples are too small for top-ranked cohort confidence. Overall score capped because colorectal/CRC disease context is not explicit.

Intent Interpretation

  • Active intent Patient tissue tumor-vs-normal Ranks human colorectal tissue or biopsy cohorts where tumor samples can be compared with normal controls.
  • Organism expectation Homo sapiens Dataset organism is interpreted as Homo sapiens.
  • Assay expectation bulk RNA-seq Dataset assay is interpreted as bulk RNA-seq.
  • Specimen assumption patient tissue or biopsy Derived specimen/source is Tissue.
  • Control-group assumption matched normal, adjacent normal, paired normal, healthy tissue control, or otherwise normal tissue control Derived study design is Tumor vs unmatched normal; likely groups are tumor sample vs normal tissue.
  • Score caps Applied when matching conditions are present non-human datasets stay below the primary recommendation band, missing colorectal/colon/rectal/CRC context stays below the primary recommendation band, biofluid and model-system datasets cannot reach Recommended by default, microarray and secondary assays are capped unless explicitly enabled, or small cohorts are capped below high-confidence recommendations
  • Warning rules 3 active warnings missing or unclear control group, unclear disease context, unclear tissue source, mixed sample types, model-system markers, secondary assay context, missing processed data, or small cohort size
  • Downgrade or exclusion reason Downgraded disease context: colorectal/GI relevance is unclear. Derived from current-intent ranking reasons and warnings.
