For new projects, a sample table can be automatically created from a tab-delimited text file. There are several advantages of creating a sample table in this manner:
- You can define multiple samples and attributes even before
...
- data has been imported, and therefore you can:
- Customize the name of your samples (and not use the automatic sample names generated based on file names)
- Import sample sheets as defined by the instrument that generated your data
- You can simultaneously create the sample table and import data, which allows you to:
- Combine several files into one sample
- Import data in located in different subdirectories
The text file must be created outside of Partek Flow (using other software such as Partek Genomics Suite, Microsoft Excel or any other text editor). A valid text file must contain is a tab-delimited text file that contains 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.
...
Navigate to the file using the browser as shown in in Figure 2. Click on Check the box next to the text file that you want to use and click Next.

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 the headers of the text file are presented and the user can be considered as a sample attribute. select the Sample ID, which to be imported and whether they are numeric or categorical.
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.

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.
...
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
