MTP (.mtp)

  • Import supports the MTP format.

Background & Context

    • Minitab portable worksheet format.
    • Statistical data format.
    • Used for exchanging and archiving statistical data.
    • MTP is an acronym derived from Minitab Portable Worksheet.
    • Plain text ASCII format.
    • Stores arrays of labeled data.
    • Developed in the 1970s as part of the Minitab Statistical Software.

Import

  • Import["file.mtp"] imports an MTP file, returning a list of lists.
  • Import["file.mtp"] returns a two-dimensional array of strings and numbers, representing the rows and columns stored in the file.
  • Import["file.mtp",elem] imports the specified element from an MTP file.
  • Import["file.mtp",{elem,suba,subb,…}] imports a subelement.
  • Import["file.mtp",{{elem1,elem2,…}}] imports multiple elements.
  • The import format can be specified with Import["file", "MTP"] or Import["file",{"MTP",elem,…}].
  • See the following reference pages for full general information:
  • Importimport from a file
    CloudImportimport from a cloud object
    ImportStringimport from a string
    ImportByteArrayimport from a byte array

Import Elements

  • General elements:
  • "Elements" list of elements and options available in this file
    "Summary"summary of the file
    "Rules"list of rules for all available elements
  • Data representation elements:
  • "Data"datasets arranged as a table
    "EventSeries"table data as an EventSeries
    "LabeledData"datasets given as a list of rules
    "Tabular"table data as a Tabular object
    "TimeSeries"table data as a TimeSeries
  • Import uses the "Data" element by default.
  • Textual information:
  • "TextData"textual data given as a list of rules

Options

  • Import option:
  • "EmptyField"""how empty cells are represented in the Wolfram System
    "TimeColumn"Automaticcolumn to use for times in "EventSeries" and "TimeSeries" elements

Basic Examples  (2)

Import summary of an MTP file:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "Summary"]

Import an MTP file as a Tabular object:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "Tabular"]

Scope  (6)

Show the Import elements available in an MTP sample file:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "Elements"]

Import the data as a list of lists:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "Data"]

Read all numerical data from this file as an array, typesetting the first 10 rows as a table:

Wolfram Language code: Take[Import["ExampleData/oldfaithful.mtp", "Data"], 10]//TableForm

Import this file as a list of rules, each representing a labeled dataset:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "LabeledData"]

Import the textual data:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "TextData"]

Import an MTP file as an EventSeries object:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "EventSeries"]

Import an MTP file as a TimeSeries object:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "TimeSeries"]

Import Options  (1)

"TimeColumn"  (1)

By default, the time column is selected automatically for "TimeSeries" and "EventSeries" elements:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "TimeSeries"]

Use the "TimeColumn" option to specify the time column:

Wolfram Language code: Import[ "ExampleData/oldfaithful.mtp", "TimeSeries", "TimeColumn" -> "DurLast"]
