Data Importing Formats

Data can be imported into PLS_Toolbox or Solo from a variety of sources using File>Import Data (or similar) menu itesm in the Workspace Browser, Analysis, and DataSet Editor windows.
Unsupported File Formats
Note: If you do not see the file type list below try the following:
- Export your data to a supported file type. Often this is delimited text, Excel, or SPC.
- If data can be exported as text, some customization can be done via our text importing tools to accommodate different formatting:
- For more information on using the textreadr function see Textreadr
- Create a custom import function Editds_userimport
- Locate a community developed importer on the Matlab file exchange.
- Other sources exist as well, for example: CDF Tools.
- Obtain a file format (specification) from the vendor. We're always happy to develop (or help develop) file importers.
- An actual specification document is great but often vendors have internally developed Matlab importers that can be used outright or be modified to work. It's also very helpful to have example files that can be used to test with.

Additional import methods may be available depending on the specific purchased options and the distributor of your copy of PLS_Toolbox or Solo. See other notes below.
Notes
- Our image processing products MIA_Toolbox and Solo+MIA include additional image-specifc importers. See Image_Importing_Formats and Constructing_Image_DataSets for more information.
- The Delimited Text File format provides a flexible way to import lots of different text file formats. For details on the format and the options available, see: Text Import Settings
- The Experiment File import method is used to import multiple data files at once along with corresponding reference values. For more information on the Experiment File format and features, see the reference page for experimentreadr.
- PLS_Toolbox users can access the importers through the autoimport command or the file import functions directly.
- In some cases you may have to use the DataSet Editor to add additional information to your dataset. For instance, you may add labels and or axis scales after you've imported the raw data. See Key_GUIs for more information on using the DataSet Editor.
- In cases involving n-way (multidimensional) data you man need to "build up" you dataset. More information about how to do that can be found here.
