Example of system search_gene

from pyrice.multi_query import MultiQuery

query = MultiQuery()
result = query.search_on_chromosome(chro="chr01", start_pos="1", end_pos="20000",
                                    number_process = 4, dbs="all", save_path="./result/")
print("Output database:", result)

Output database:

Example of system query_by_ids

from pyrice.multi_query import MultiQuery
		
query = MultiQuery()
result = query.query_by_ids(ids=["Os08g0164400", "Os07g0586200"],
                            locs=["LOC_Os10g01006", "LOC_Os07g39750"],

        'status': 'success',
        'arguments': {},
        'comments': ['Results found for: annotation; queries: ; filters: '],
        'data': [{...}]

   ...
}

Example of Build Dictinary Module

from pyrice.build_dictionary import update_gene_dictionary, update_rapdb_oryzabase

update_gene_dictionary()
update_local_database(rapdb_url, oryzabase_url)

Example of Search Module

You have to save file as .pkl and re-load it again to use search function.

from pyrice import utils 
import pandas as pd

df1 = pd.read_pickle("./result1/data/db.pkl")
df2 = pd.read_pickle("./result2/data/db.pkl")
df = pd.concat([df1,df2])
result = utils.search(df,"Amino acid ")

Example of SQL Query

You can execute a SQL query over a pandas dataframe. You have to install package Pandasql. The variable name is same with the table name in SQL query. Next, follow the code below to run SQL query:

import pandas as pd
from pandasql import sqldf

data = pd.read_pickle("./result/data/db.pkl")
data = data.astype(str)
sql = "SELECT * FROM data WHERE `oryzabase.CGSNL Gene Symbol` = 'TLP27' or `gramene.system_name` = 'oryza_sativa'"
pysqldf = lambda q: sqldf(q, globals())
print(pysqldf(sql))

The variable name must be same with the table name in SQL query.
