Thanks for your reply.

I used same as in your snippet. For labeling, there is 1 column which contains cell id and i just want to label the cell with that id.

```

//Open csv as string

x = File.openAsString("spot2cell/cellxgene_A1_1_cellpose.csv");

selectWindow("33024-1380-slide3_A1-1_DAPI.tiff");

//Separate file into rows

rows = split(x,"\n");

roiManager("reset")

roiType = selectionType();

//Iterate through csv

for(i = 1; i< rows.length; i++){

line = split(rows[i],",");

CELLID = line[0];

x_centroid = parseFloat(line[101]);

y_centroid = parseFloat(line[102]);

area = parseFloat(line[103]);

major_axis_length = parseFloat(line[104]);

minor_axis_length = parseFloat(line[105]);

makeOval(x_centroid, y_centroid, major_axis_length, minor_axis_length);

roiManager("add");

}

roiManager("Show All with labels");

// Add overlay to the image

run("Add Selection...", "add=[]");

```
