描述----------Description----------
The MAPPER RPC interface allows you to retrieve a set of predicted transcription factor binding sites from the MAPPER database through a simple HTTP request. This package provides a function to retrieve predicted TFBS from R.
映射器RPC接口可以让你找回了一套预测转录因子结合位点的映射数据库,通过一个简单的HTTP请求。这个包提供了一个函数来预测TFBS信息检索从河
用法----------Usage----------
readMAPPER(stub = paste(urlpath, "db-rpc?", sep = ""), ...)
参数----------Arguments----------
参数:stub
stub – a string giving the URL handle up to the db-rpc selector (optional)
存根 - 给URL字符串处理DB-RPC选择(可选)
参数:...
... – all the query parameters (see Details).
... - 所有的查询参数(见详情)。

详情----------Details----------
Currently (9/10) the RPC interface to MAPPER defines the following parameters. You can use any of these as keywords (with bindings supplied using "=", e.g., gene="CRP") to the readMAPPER function.
目前(9/10)MAPPER公司的RPC接口来定义以下参数。您可以使用任何这些作为关键字(绑定提供使用“=”,例如,gene="CRP")readMAPPER函数。
gene - you can use either NCBI GeneID or mRNA accession number; gene names should work too, but this is not recommended because there often are multiple forms of the same gene. [required, unless 'list' is specified]
基因 - 您可以使用NCBI的GeneID或基因表达加入的数量;名工作过,但不建议这样做,因为经常有同一基因的多种形式。 [必需的,除非指定名单]
models - a comma-separated list of model names (to restrict the output to these models only) [required, unless 'list' is specified]
模型 - 一个模型名称的逗号分隔的列表(限制输出到这些模型只)[必需的,除非指定名单]
score - the score threshold (0 by default)
比分 - 比分阈值(默认为0)
perc - the percentile (one of 50, 80, 85, 90, 95). Only hits with scores above the desired percentile for each model are returned.
PERC - 百分(50,80,85,90,95)。每个模型所需的百分以上的分数只命中返回。
eval - the E-value threshold (25 by default)
EVAL - E值的阈值(默认为25)
pbases - how many basepairs to look at (default: 2000). See pstart.
pbases - 如何看待许多碱基(默认:2000)。看到PSTART。
pstart - what pbases is relative to (either T for transcript start or C for coding sequence start - remember that in the db we have hits for the region from 10,000 bp upstream of transcript start to 50bp after coding sequence start)
,PSTART - 是相对什么pbases(无论誊启动或编码序列开始ç的T - 记住,我们在DB从10,000 bp的命中该区域上游转录启动编码序列的开始后,以50个基点)
sort - how to sort the results: either M (by model accession), N (factor name), E (by E-value), S (by score), P (by position, the default)
排序 - 如何排序的结果:要么米(模型加入),氮(因素的名称),电子(E值),S(得分),磷(位置,默认)
org - two letter organism code
ORG - 两个字母的有机体代码
list - returns a list of all TF names with the corresponding model accession numbers. All other parameters are ignored.
列表 - 返回所有的TF名称与相应的模型加入数字列表。所有其他参数将被忽略。

值----------Value----------
An instance of the mapperHits class.
