For new projects, a sample table can be automatically created from a tab-delimited text file even before any files are imported. A valid text file must contain at least one column that has unique entries (to be used as Sample IDs) and may have additional columns with sample information such as experimental attributes.
In a Data Tab where no samples have been imported yet (Figure 1), click the Assign sample attributes from a file button.
Navigate to the file using the browser as shown in in Figure 2. Click on the box next to the text file that you want to use and click Next.
Creating a Sample Table without Data Import
Text files that contain only sample information and attributes such as the one shown in Table 1 can be imported to create a sample table with no associated files. For this type of import, the text file may be located in either the Partek Flow server, My computer, or from a URL (Figure 2).
During import, Partek Flow will recognize columns that contain unique entries and suggest those as possible Sample IDs.
In Figure 3, each row rows in the table came from the columns of the text file can be considered as a sample attribute. The headers from the text file are in the first column as Attribute names, which can be edited. Example entries are shown
In the example in Figure 3, the columns for "Sample name" and "Freezer Location" are both unique and the radio button can be used to select the preferred sample ID.
You can also unselect the columsn you do not wish to import
Numeric can be imported as smaple attributes
Each row is now a sample but is not associate with any file. Click Show data files to expand the table and associate files. For more details see the relevant section here.
Creating a Sample Table with Data Import
A feature of creating the sample ability to combine this step with data import ... the additional feature of importing samples during table creation (described below) are currently only available if the text file is in the Partek Flow Server.
can only be at the same time as creating the sample table) can only be performed if
a sample table that also includes the locations of filenames can only be based on the sample table (as described later in this section)
The text file must be in the server or a folder that is readable by the partek flow server. the text file contains filenames
A valid text file:
TABLE TEXT FILE NO PATH
useful if there are many files for one sample, You can add as many columns as you want on the right
Flow recognizes sees that some columns in your text file are filenames of
In the example above, the text file and Data files are in the same directory. If your samples are in different subdirectories, YOU CAN USE PATHS. RELATIVE OR ABSOLUTE
Relative to the text file
Absolute path
FIGURE NAVIGATION SHOW THAT THE DATA IS IN DIFFERENT DIRECTORY AND the directory structure starts with /home/directory....
TABLE ABSOLUTE PATH
you must write the path this way
