1.4. Access to datasets in the database

When you access https://jmorp.megabank.tohoku.ac.jp, the top page of the jMorp website appears.

../../_images/access_to_datasets-top.en.png

There are roughly three blocks on the top page (keyword search, genome browser, and category index).

1.4.1. Keyword search

You can use the keyword search panel in the upper left corner to conduct a keyword search on all of the data in the jMorp. You can use the following kinds of keywords:

Note

To navigate to the actual search results page, click on any of the example search keywords below. Please give it a try to see what kind of page you get.

Category	Query example
Gene Symbols	ALDH2 / NFE2L2 / GATA1
Ensembl Gene ID	ENSG00000115415
UniProt ID	P05091
PDB ID	5l13
dbSNP ID (rsID)	rs671 / rs6721961 / rs1801133
Gene symbol + HGVS.p, RefSeq ID + HGVS.p	TP53 P72R / ALDH2 p.Glu504Lys / NP_000537 P72R / NP_000681 p.Glu504Lys
Position / Region on a reference genome	chr2:210477778 / chr1:12345-23456
Metabolite name	Glycine / Creatinine
m/z and retention time of metabolites analyzed by MS	100<mz<200 / 1<rt<3
GWAS trait name	BMI

At the time of this writing, for example, a search for Creatinine yields the following results:

../../_images/access_to_datasets-creatinine.en.png

The search results from the metabolome dataset are displayed at the top of the search results page. In the metabolome dataset, creatinine was examined using a variety of techniques, including NMR, LC-MS, and GC-MS, and each of these analyses is represented as a separate entry.

The search results from the GWAS dataset are presented at the bottom of the search results page. You can view the results of analyses using Creatinine as a GWAS trait among the GWAS analysis results stored in jMorp by clicking the link in this panel. It is possible to conduct a cross-search on the data stored in jMorp, as in this example, by using the keyword search panel on the top page of jMorp.

Note

Since the keyword Creatinine matches multiple entries, the search result page like above is displayed. However, if an input keyword matches just one jMorp entry, the search result page is not shown, and you are instead taken directly to the entry page.

1.4.2. Genome browser view

You can browse the genome-related data in the genome browser by clicking the link on the bottom left of the jMorp top page. There are three different types of genome browsers available now: GRCh37/hg19, GRCh38/hg38, and JG3.0.0. The genome-related data stored in jMorp uses different reference genomes for analysis, and the data that can be browsed differs depending on the selection of genome browsers.

1.4.3. Category index

jMorpトップページの右側には、jMorpに収録されているデータセットの一覧が並んでいます。データセット名をクリックすると、そのデータセットに収録されているエントリの一覧を見ることができます。例えば、 Metabolome 2024 をクリックすると下のようなテーブルが表示され、メタボロームデータセットに含まれる代謝物の一覧を見ることができます。

../../_images/access_to_datasets-metabolite_list.en.png

更に代謝物IDをクリックすることで、その代謝物の詳細情報を閲覧することができます。

The category index is the best option if you want to quickly see what kind of data is contained in jMorp.

Note

For categories with a lot of entries, like Genome Variation (SNV/INDEL), lists of entries are not available. Please make use of the keyword search and genome browser views.
