* Database Information WARNING: This document contains information on the GN databases which will change over time.

From the code it looks like GN2 uses a mixture of Redis and sqlalchemy to keep track of logged in sessions (see gn2/wqflask/wqflask/user_manager.py) and cookies through a user_uuid in model.py.

This is a terrible table but it works well (RWW March 2016). It is used in combination with the crucial TRAIT DATA and ANALYSIS pages in GN1 and GN2. It is also used by annotators using the UPDATE INFO AND DATA web form to correct and update annotation. It is used by Arthur to enter new annotation files and metadata for arrays, genes, proteins, metabolites. The main problem with this table is that it is doing too much work. Initially (2003) this table contained only Affymetrix ProbeSet data for mouse (U74aV2 initially). Many other array platforms for different species were added. At least four other major categories of molecular assays have been added since about 2010. 1. RNA-seq annotation and sequence data for transcripts using ENSEMBL identifiers or NCBI NM_XXXXX and NR_XXXXX type identifiers 2. Protein and peptide annotation and sequence data (see BXD Liver Proteome data, SRM and SWATH type data) with identifiers such as "abcb10_q9ji39_t311" for SRM data and "LLGNMIVIVLGHHLGKDFTPAAQAA" for SWATH data where the latter is just the peptide fragment that has been quantified. Data first entered in 2015 for work by Rudi Aebersold and colleagues. 3. Metabolite annotation and metadata (see BXD Liver Metabolome data) with identifiers that are usually Mass charge ratios such as "149.0970810_MZ" 4. Epigenomic and methylome data (e.g. Human CANDLE Methylation data with identifiers such as "cg24523000") It would make good sense to break this table into four or more types of molecular assay metadata or annotation tables) (AssayRNA_Anno, AssayProtein_Anno, AssayMetabolite_Anno, AssayEpigenome_Anno, AssayMetagenome_Anno), since these assays will have many differences in annotation content compared to RNAs. Some complex logic is used to update contents of this table when annotators modify and correct the information (for example, updating gene symbols). These features requested by Rob so that annotating one gene symbol in one species would annotate all gene symbols in the same species based on common NCBI GeneID number. For example, changing the gene alias for one ProbeSet.Id will changing the list of aliases in all instances with the same gene symbol. If the ProbeSet.BlatSeq (or is this ProbSetTargetSeq) is identical between different ProbeSet.Ids then annotation is forced to be the same even if the symbol or geneID is different. This "feature" was implemented when we found many probe sets with identical sequence but different annotations and identifiers. select count(*) from ProbeSet limit 5; +----------+ | count(*) |

Suggestions on the schema page: "StrainId" should be "CaseId" or "SampleId". "ProbeSetData" should probably be "AssayData" or something more neutral. *** Comments I think the ProbeSetData table should be generalized to a 'phenotypes' table with an 'sample_id' column and a 'value' column. A new table 'samples' will link each sample against an 'experiment', an 'individual' and which in turn can link to a 'strain'. Experiment is here in a wide sense, GTex can be one - I don't want to use dataset ;) This means a (slight) reordering: phenotypes: (id), sample_id, value samples: experiment_id, individual_id experiments: name, version individual: strain_id strains: species_id species: ... ProbeData is also interesting, because it has the same structure as ProbeSetData, but only contains microarrays. This tables should be one (when we clear up the cross-referencing) as they both contain phenotype values. Both are large tables. PublishData is another phenotype table with values only which can be merged into that same table. So we have phenotype data in 3 tables with exactly the same layout. There is also TissueProbeSet*, but we'll ignore those for now. I think we should merge these into one and have the sample ref refer to the type of data (probeset, probe, metabolomics, whatever). These are all phenotype values and by having them split into different tables they won't play well when looking for correlations. ProbeSet contains the metadata on the probes and should (eventually) move into NoSQL. There is plenty redundancy in that table now. I know it is going to be a pain to reorganize the database, but if we want to use it in the long run we are going to have to simplify it. ** ProbeSetFreeze and ProbeFreeze (/dataset/name.json)

Phenotype datasets appear in two major forms in the database and we want to present them as one resource. Dataset names are defined in ProbeSetFreeze.name and Published.id -> publication (we'll ignore the probe dataset that uses ProbeFreeze.name). These tables should be meshed. It looks like the ids are non-overlapping with the publish record IDs starting at 10,001 (someone has been smart, though it sets the limit of probesets now to 10,000). The datasets are organized differently in these tables. All published BXD data is grouped on BXDpublished with the publications as 'datasets'. So, that is how we list them in the REST API. To fetch all the datasets we first list ProbeSetFreeze entries. Then we list the Published entries. ** Fetch genotype information *** SNPs The SNP count info for the BXD is calculated like this #+begin_src python while startMb= %2.6f AND Mb < %2.6f AND StrainId1 = %d AND StrainId2 = %d """ % (chrName, startMb, startMb+stepMb, strainId1, strainId2)).fetchone()[0] SNPCounts.append(snp_count) startMb += stepMb #+end_src : select * from BXDSnpPosition limit 5; +------+-----------+-----------+----------+ | Chr | StrainId1 | StrainId2 | Mb | +------+-----------+-----------+----------+ | 1 | 2 | 3 | 0.002477 | | 1 | 2 | 3 | 0.002592 | | 1 | 2 | 3 | 0.00283 | | 1 | 2 | 3 | 0.002994 | | 1 | 2 | 3 | 0.003299 | +------+-----------+-----------+----------+ Other SNP tables containing select * from SnpSource limit 5; Empty set (0.00 sec) select * from SnpAll limit 5; Empty set (0.00 sec) mysql> select * from SnpAll limit 5; Empty set (0.00 sec) mysql> select * from SnpPattern limit 5; Empty set (0.00 sec) mysql> select * from SnpSource limit 5; Empty set (0.00 sec) Hmmm. This is the test database. Then there are the plink files and VCF files. * Optimize SQL? We were facing some issues with slow queries. A query was really slow on Penguin2: : time mysql -u webqtlout -pwebqtlout db_webqtl < ~/chunk.sql > /dev/null : real 0m13.082s : user 0m0.292s : sys 0m0.032s Runs in 1s on Tux01 and 13s on P2, why is that? The gist of it was increasing an InnoDB cache size(!) Interestingly, Penguin2 is running InnoDB on a much slower storage. It has more indices that Tux01(?!). Probably due to things we have been trying to make the datatables faster. Meanwhile the query is one with many joins: #+begin_src sql SELECT ProbeSet.Name,ProbeSetXRef.DataId, T4.value, T5.value, T6.value, T7.value, T8.value, T9.value, T10.value, T11.value, T12.value, T14.value, T15.value, T17.value, T18.value, T19.value, T20.value, T21.value, T22.value, T24.value, T25.value, T26.value, T28.value, T29.value, T30.value, T31.value, T35.value, T36.value, T37.value, T39.value, T98.value, T99.value, T100.value, T103.value, T487.value, T105.value, T106.value, T110.value FROM (ProbeSet, ProbeSetXRef, ProbeSetFreeze) left join ProbeSetData as T4 on T4.Id = ProbeSetXRef.DataId and T4.StrainId=4 (...) left join ProbeSetData as T110 on T110.Id = ProbeSetXRef.DataId and T110.StrainId=110 WHERE ProbeSetXRef.ProbeSetFreezeId = ProbeSetFreeze.Id and ProbeSetFreeze.Name = 'HC_M2_0606_P' and ProbeSet.Id = ProbeSetXRef.ProbeSetId order by ProbeSet.Id #+end_src And is blazingly fast on Tux01 and (now) fast enough on Penguin2.
