If ArrayStar has difficulty importing your data, one of the following errors may appear:
"The data file ... contains # duplicate genes within itself."
This means that the data file cannot be loaded because a unique Gene ID has not been designated for each gene in your file. Try selecting additional columns as "Gene ID" in the Data Import Wizard. Or open your delimited text file in a program such as Microsoft Excel and add a column with a unique ID for each row in your file (such as 1, 2, 3, etc.). Then, designate your newly added column along with other columns containing gene identifiers as "Gene ID" during the import.
"The data file ... contains # genes which are ambiguous with regard to the project."
This error may occur when multiple files in your project have different columns designated as "Gene ID" and some of the genes in one file match multiple entries in another.
At least one Gene ID column in the data file you are importing must match with the Gene ID chosen for the existing datasets in your project. Make sure you selected the correct file to import and designated the correct column(s) as "Gene ID." If necessary, manually edit your file in a program such as Microsoft Excel to add a new Gene ID column that matches the existing Gene IDs in your project. Then, designate your newly added column along with other columns containing gene identifiers as "Gene ID" during the import.
"The data file ... contains # genes, none of which match the genes already loaded in the project."
This means that none of the data in the file being imported matches the data that is already in your project.
At least one Gene ID column in the data file you are importing must match with the Gene ID chosen for the existing datasets in your project. Make sure you selected the correct file to import and designated the correct column(s) as "Gene ID." If necessary, manually edit your file in a program such as Microsoft Excel to add a new Gene ID column that matches the existing Gene IDs in your project. Then, designate your newly added column along with other columns containing gene identifiers as "Gene ID" during the import.
There was an error while importing. Cannot access a disposed object. Object name: 'ProjectSetupWizard'.
This error indicates that you do not have enough RAM to import the data file in question. In general, more RAM is needed to import text files vs. SeqMan NGen projects, or whole-genome data sets vs. smaller data sets. To close the message, click OK.
